Wallowing Beast

Our old class C on the chev chassis needed upper control arm bushings. Didn't have that many miles but were worn out.

A good addition and ease of checking your tire pressures are a set of extended valve stems. Tire Man or borg make them and you can check the air pressure in all tires quickly. The Tireman valve stems come with Flow Thru valve caps that makes the chore even easier and faster.

You should definitely weigh the motorhome. If you can get each corner, that's ideal. Not all scales weigh all four corners, you might have to settle for front axle and rear axle weights. Then check the tire manufacturer's specs on tire pressure.

You should also have the alignment checked and the ball joints checked. I noticed on our motorhome at the end of the year last year that the front was a little loose and figured it was time for an alignment. Turned out the ball joints were shot. Had them replaced, the front end aligned and the motorhome drives great now. No movement at all.

Our motorhome came from the factory with front and rear anti-sway bars. It amazes me that anything larger than a mini-suv comes from the factory without both front and rear anti-sway bars. A rear anti-sway bar will help with body roll and make it feel more stable.

What tire pressure are you running?

I have not weighed it but the sticker says 9400lbs unloaded. The tires are load rated E. The fronts are at 55psi but I can't even see the rear valves to get a pressure gauge on them. There must be a way to measure the rears?

Consider how you are loading it. Lightweight stuff goes high, heavy stuff goes low. Water tank is low - is it full? That might help.

RV's are heavy and top heavy with stiff rear springs. Some claim much better handling and ride with costly after-market improvements. You will get recommendations on stabilizer bars, alignment changes, air bags, springs, etc.
This is a common subject, read the pertinent "stickies" and use search for many relevant threads.

A rear sway bar will make a lot of difference in the way it handles and will help in the sway and leaning. Also check the shocks,a good set of Bilsteins really will help too.

My Chevy based Class C has front and rear sway bars and a new set of Bilsteins and handles well.Others of the same year that were not built on a Workhorse Chassis,they didn't come with rear sway bars,did have a problem of control.

Have you weighed the rig? Four corner plus front and back.
