driving my new class c

[Danford50]

I drove my new rig home today, it was a 80 miles trip back home, I noticed that it felt like the front of the truck was wandering or it felt loose has anyone felt that in there class c and if so could you tell me how you fixed it.

Excellent advice from "j-d". I only ride with 65 PSI in the front tires but 80 PSI in the rear tires due to the actual weight carried on each axle. With the long overhang on most Class C motorhomes, it's easy to have too much weight behind the rear axle and that weight acts to lighten the weight on the front axle which can cause poor handling. I moved almost 100 lbs of "stuff" from the rear compartments to storage further forward after weighing my rig the 1st time after it had been fully loaded. Having the correct distribution of weight and the correct tire pressures makes a BIG difference in the handling.

Wandering E450

There are dozens of threads about this. There's good discussion in a recent thread with topic "swaybars" and another about being pushed around by trucks.

What Chassis is it on? Particularly if your chassis is Ford E350 or E450, the "80" you mentioned may be part of your answer.

Especially, again, with Ford, VERY important to inflate front tires to what a Weight-to-Pressure Chart calls for based on ACTUAL SCALE Weights. Load your RV up as you would for a trip, people and all. Get Thee to a Truckery (Truck Stop/Travel Cener) and weigh it on their CAT Scale. If you tow something, pull that up onto the scales too. People on board for the weighing!

Then go to the Air Station and adjust your tire pressures. Your sidewalls are going to be marked "80 PSI MAX" and they're pretty much fitted to your chassis with no excess capacity. So your Chassis label will also say "80" but that only applies to max rated axle loadings!

If somebody aired all six to 80, it's probably too much in front and your coach will wander, even if everything else is OK. Excess pressure in the rear tires...pretty much just makes it ride harder, but little effect on wandering.

Check all SIX tires. Look to see if there are flexible valve stems or extension tubes/adapters. You need Solid, One Piece Valves like These from BORG, also available at Camping World.
