How To Choose The Best Chassis For You

The explosive growth in chassis innovations has introduced a new dynamic to the selection process for your next RV. There was a time when RVers would simply accept the chassis and engine the manufacturers provided with their motor homes. Very little consideration was given to the platform that the vehicle was built on because there were only a few products available.

However, over the past five years the industry has seen a dramatic increase in the number of proprietary and customized chassis offerings being developed in concert with the RV manufacturers. What was once a given, is no more! Educated RVers are now looking very closely at the chassis and engine offerings and are studying the differences that will eventually determine their satisfaction with respect to the level of comfort, performance and maneuverability they are going to expect from their RV investment.


Roadmaster Chassis, a division of Monaco Coach Corporation, does only one thing – it builds the chassis for Monaco’s family of product lines. Each chassis is engineered to the exact specifications that will provide the safety, reliability and performance required by the RV model that will be built on it. Products in the Monaco, Holiday Rambler, Beaver and Safari product lines are built on one of seven Roadmaster Chassis platforms.

Their flagship chassis is the S-Series and depending on the model and floor plan, you may find your rig powered by a Cummins® ISL 425 hp engine with 1200 ft-lbs of torque at 1300 r.p.m. mated with an Allison® 3000 MH 6-speed transmission, a Detroit Diesel Series 60 engine offering 515 hp with 1650 ft-lbs of torque at 1200 r.p.m. coupled with an Allison 4000 MH 6-speed transmission, or a Cummins ISX 525 hp engine that also delivers 1650 ft-lbs of torque at 1200 r.p.m. and accompanies an Allison 4000 MH transmission.

Roadmaster Chassis products include cushion air-glide suspension that enables the left and right sides of the suspension to operate independently of each other. This provides the benefits of independent suspension without the complexity, cost and higher maintenance associated with conventional independent front suspension. Roadmaster Chassis is also known for its outboard mounted air bags that are placed approximately seven and a half feet apart on most models, providing a wider and more stable platform. The active suspension automatically adjusts the pressure of the air bags as you drive and virtually eliminates nose-diving and the side-to-side body sway associated with high wind conditions, curvy roads and emergency maneuvers. The power steering box on all Roadmaster chassis provides a 50-degree front wheel cut in both directions for easier maneuverability.

Why not do a test of say four or five of the 45 ft Motorhomes with the different chasis you describe and rate them for power, ride, acceleration etc. Use the same general HP as option, but all the same power. I can t test them all!!

Most of these type of test, ride, handling etc.. articles are subjective, not scientific. Therefore it is the opinion of the person doing the test. As an example: Some people like a soft ride while others may like a more responsive ride which would require a stiffer suspension. Some like very tight steering while another will like a little play in the steering. One person will want plenty of power and the next will be looking for economy. I think the best solution is to read all the reports and claims put out by each individual manufacturer, come in and test drive the chassis to determine which one fits your needs.
I am sure ther are plenty of people out there that can give us their opinions also! Lets here it!

I have to agree with Steve on this one. I talk to and drive a lot of different folks in all the different chassis available. The opinion of the ride and drive is very personal depending on the expectations of the RVer. Much is made of the number of air bags, straight axel or independent front suspension and a plethora of other options. The first thing to consider is your budget and what platforms are available at a particular price point. From there you have to try them for yourself. You are the only one who can say if it handles the way you want it to or if the ride feels comfortable, secure or responsive. Everyone has a different expectation and opinion.

Ride, handling and driveability preferences can only be determined by the individual. Test drive both chassis to determine which one you prefer rather than depend on someone's opinion or comparison. Most importantly it is how the body is built on the chassis and how it is loaded by the owner that controls the ride or driveability. Also be sure to compare empty weight to gross vehicle weight rating (GVWR). A Federal ID tag is required to be located in the cockpit area with this information or it can be found in the sales literature.This determines how much of your stuff you can load in the motorhome. Any chassis that is overloaded will not handle properly.
Both of these chassis have been specially designed by the motorhome manufacturer (Monaco and Winnebago) so there is more involved than just the choice of chassis.

I bought a 2011 Bounder with a Ford V-10. Worst mistake I ever made. Traded it in for a 2003 Southwind with a Workhorse W-22 already and am happy again. The Ford was underpowered and noisy.

I own a towing company that has cash for junk cars division. I have recently purchased a 1999 Windsor and I LOVE it. Diesel Pusher is the ONLY way to go.
