THE PREVOST CHASSIS

The Prevost chassis is, quite simply, the ultimate motorcoach chassis.

The Prevost chassis, the benchmark of strength and safety, is constructed on a unibody structure. On uneven roads, the integrated Prevost chassis remains strong and rigid, preventing any twisting of the chassis floor. Cabinetry, flooring and appliances stay stable – an important factor in keeping your motorcoach safe for years to come.

Goto tenglong to know more.

On other coaches, the chassis is the lower structure, from the floor down – the walls, ceiling and caps are added later. It is not uncommon for other RV chassis to torque, or twist, when encountering uneven road surfaces. This twisting moves through objects attached to the floor such as cabinetry, tile and appliances.

Prevost Chassis: Engineered to be a motorcoach.

The majority of the Prevost chassis is made from stainless steel, welded together to form one top-to-bottom, corrosion-resistant structure. Other RVs often use steel in their chassis, and even coat the frames in a protective spray coating, but the added-on walls and ceiling are made from steel, aluminum, wood or any combination – never matching the stability of our unibody frame.

Prevost engineers work closely with Marathon to accommodate the high demands of luxury motorcoaches. We work together on everything, including slides and other modifications, all the while maintaining the high standards of strength and safety found in a commercial bus.

The company is the world’s best Bus chassis supplier. We are your one-stop shop for all needs. Our staff are highly-specialized and will help you find the product you need.

The Prevost chassis is built to travel more than a million miles. Our chassis is built to the same exacting standards as Prevost’s commercial bus chassis.

Unlike other RVs, the Prevost chassis is designed to travel well over a million miles. You’ll only need to stop to change drivers, take on fuel and passengers or get regular maintenance.

Prevost’s aim is to provide customers with the highest quality commercial bus and motorcoach chassis that will stand up to the rigors of all-weather travel. Safely moving people. Every day.

PREVOST CHASSIS FEATURES

• The best of both worlds, Marathon Prevosts were specifically engineered for RVers while keeping the pedigree of a safe, smooth and robust commercial bus.
• The Prevost chassis handles better and provides better responsiveness because of the inherent strength of this fully-welded unibody chassis, which is rarely impacted by twists and turns that damage other chassis.
• There are two 45′ chassis available: The H3-45 with sleek modern sides and the most storage of any RV on the road; and the X3-45 with classic stainless ribbed sides and 89″ of headroom.
• The unibody structure is the strongest, safest and most durable in the motorhome industry.

• A Prevost chassis is assembled with robust 304-grade stainless steel, known for its structural integrity, durability and corrosion resistance.
• The proven Volvo D13 engine has excellent torque even at low RPM, and engine emissions and improved air quality are beyond EPA regulations.
• Transmission output retarder braking system.
• Aware adaptive cruise control, which adjusts the cruise speed to maintain a safe following distance, including features like following distance alert and impact alert.
• State-of-the-art tire pressure monitoring system for both heat and pressure.

• Slide-outs with all-around scenic windows.
• Frameless side windows are full-height and blended with the sides for a clean look on the outside and a panoramic view on the inside.
• The Prevost electronic stability program: provides assistance when the unexpected happens with increased protection against coach rollovers; and provides better control of the coach.
• Easy-to-use mobile apps for service location, warranty services, technical manuals and service bulletins.

PREVOST CHASSIS ADVANTAGES

• Prevost’s own “zero-tolerance” assembly precisely calibrates the alignment and positioning while each piece of stainless steel structure is being welded. This means that every Prevost coach has maximum resistance to stress, bending and buckling over the course of its lifetime.
• The incredible engineering of the top-to-bottom welded frame allows Prevost to get the maximum rigidity benefits with the minimum weight added.
• Prevost independent suspension is designed and built by Prevost.

• Anti-lock braking system is sized and calibrated to provide the safest, shortest stopping distance across a wide range of road and weather conditions.
• Largest service network of any North American motorhome builder with 150 service center providers, 14 service centers and 13 field service managers.
• Large storage bays provide unsurpassed square footage of under-floor cargo space.
• Patented Prevost beam adds strength so the vehicle can accommodate more slides and more floor space without reducing space for amenities and storage.

• Factory-integrated telematics allows the driver to monitor the engine, transmission, ABS system, tire pressure monitoring system, diesel particulate filter, Prevost electronic stability program and more from the integrated dash display using Prevost Liaison.
• The Prevost PRIME system is an energy management system that reduces fuel consumption by using the engine down time (braking, deceleration and other negative torque situations) to charge the batteries and compress air.

I am sure it did make a HUGE difference in the way his Skoolie drove down the road. Your friend was lbs over the rated capacity of the front axle much less the steer tires BEFORE he made his changes. This bus was definitely an accident waiting to happen! He should be glad he has a good friend such as yourself who is concerned for his SAFETY when making suggestions for his build!

Unfortunately it would not surprise "me" if your friend was "Normal" when it came to building a Skoolie. Many of these builds I see here on this site scare me to "Death" when you look at all the weight builders add to their bus and the location on the chassis where the weight is added within the bus.

Clearly very few Skoolie builders ever take into consideration the front axle and front steer tire capacity ratings when designing & building their Skoolie. I hate to say what should be obvious however "Safety First" should be your "First" consideration when designing and building your Skoolie for you and your family!

Cowlitz definitely knows buses. the body is NOT part of the chassis structure. we build a lot of tiny houses on school bus chassis, there are a lot of reasons why this is a great starting platform. first the suspension and brakes are superior to trailers. the chassis is much stronger. the chassis can hold more weight safely. tires are rated for the load. So as you can see, there are a lot of reasons to use a bus chassis. we have built over 65 tiny houses on bus chassis and we are currently building our mobile RV shop on a bus chassis with a TINY HOUSe. the main reason I'm doing this is ,people always want to see one but we sale everything we build before its finished. so we are building our own to have to show people what they are like. so yes you very much can build a tiny house on a bus chassis. not only build but build a very safe and structurally sound house.

Very interesting. I'd love to see what sorts of things you've done with bus chassis if you share photos anywhere online we build professional tiny houses on bus chassis all the time, the advantages are huge!
better breaks, better tire ratings, better safety, better better better!!!!! you cant go wrong
the bus body is built to be a structural box, but its independent of the bus chassis. so we cut the body off right behind the drive area and build a tiny house on the back 30 feet. we are building one now that is a short bus to use as a mobile shop for our mobile rv services. its an international chassis DT 360 (250 HP) with MT 643 Allison ( this combination will fly! over 80 on the highway) but we are adding a twist to this build, we are using a chevy truck cab and front clip so it will have the front end of a
chevy truck and a tiny house on the back. we are planning to build this unit this year.

How does your Tiny Home product differ from a DIY RV?

Are the necessary safety inspections performed by a licensed state or county entity?

Are "homeowners" able to obtain:
- Certificate of Occupancy from their local AHJ?
- Homestead tax Exemption from the Property Appraiser?
- Homeowners Insurance?

What additions or changes advance the bus from an RV to a tiny House?

Are we simply redefining "stationery RV" and replacing it with "tiny house"?
You used the word "professional", meaning licensed/bonded/insured Electricians, Plumbers, HVAC, permitted, inspected & certified? Not amateurs, Pros.

A manufactured "Park Model" RV can receive all of the aformentioned homestead inspections and benefits, the same as an on-slab, brick & mortar home. The park model rv manufacturers have upgraded their product and negotiated the licensing & certifications to define their product as a Perminant Residental Structure.
Did you?

What sort of gearing is getting you 80+ on the highway? I've got 3.42 to accomplish this. It has a 3.42 diff. but the real reason it runs so fast is the fact the MT trans locks up the converter. so you don't have slipping. the engine was a non after cooler engine rated at 225 horse. I added a after cooler and added propane injection for the hills/ mountains the injection comes in at 6 pounds of boost so when i'm running under 6 pounds boost it is running strictly on veggie oil or engine oil or wheat ever i'm running in it at the time. but when the hills come up (mountains), it will kick in and just increase torgue like a nomad!
