Fully loaded for travel what would be the approximate weight of 24 ft Class C.
I roll at 12,500-12,700 with approx. 50 gals of on board water.
24 ft 2018 Sunseeker on top of a Ford E450
Additions I have :
Alignment with front kit
Bilsteins up front
Koni FSD's rear
Supersteer rear track bar
Sometime soon ….air bags w/2 lines and on board compressor to gain some rear end clearance.
BTW, with all the leftover payload my DW can carry all the shoes and extra hair dryers that her heart desires. :)
Hmmm .... are you sagging in the rear a bit?
Our 2005 24 foot Class C on it's E450 doesn't sag in the rear. In fact, although I've never precisely measured it, I think we could be ever so slightly high in the rear - probably less than an inch though. That's with the spare tire, 55 gallons of gas, and 45 gallons of fresh water in the rear behind the rear axle ... plus sometimes a load of rocks (we're part time rockhounds) midway between the front/rear axles. However, Winnebago installed the heavy refrigerator, Onan generator, and 18 gallon propane tank about midway between the front/rear axles - which does leverage their weight to help reduce any weight-bias behind the rear axle.
The stock front and rear sway bars have always seemed fine in controlling side-roll action - even in high cross winds. It makes sense that side-roll control is also being helped by the rear FSD shocks switching into their low frequency stiff damping mode in these situations. We have never experienced any tail wagging, which I wouldn't expect should be an issue on a 24 foot Class C, even though our wheelbase is only 158 inches. Our E450's stock front/ear sway bars may help a bit with tail wagging - but I'm not sure on all the geometry dynamics involved with sway bars. Our original stock front steering shock absorber is still in place after ~71K miles and the service tech says there is no need to replace it yet.
FWIW, I do run 75-80 lbs. of pressure in the rear duals at all times, even though the tire pressure weight charts probably would show that much pressure is not necessary for the weight in the rear of our Class C. I do this because one of the benefits of high tire pressures is a more rigid tire that helps to reduce side-to-side cross section shape-changing of the tires - and any of this kind of tire wiggling motion is going to get translated right up into the vehicle - and of course is not good in the rear of an RV with overhang back there. (High tire pressures also reduce internal heat generation in tires due to the resultant reduced flexing of the tire sidewalls ... and of course heat is a hugh enemy of tire life and safety.)
