We had a 24-ft C on 158" WB. It drove very well, but it was the pre-1992 chassis. Front Axle was Twin I Beam but it had kingpins not ball joints. Along with a better front sway bar arrangement than 1992-2007 E-Series.
I don't hear the handling complaints about the 24-footers that I do from owners of longer coaches. Biggest mistake Ford owners do, is air up the front tires to the pressure on the sidewall, or the door jamb decals.
As others've said, be sure the tires haven't aged out of usefulness. If they're Load Range "D" with a max pressure of 65 PSI, I'll guess those tires are OLD. Just about all the new ones are "E" and 80 PSI. 65 would be max load on the front axle, 4600 lbs, and I'd guess you have 1000 less than that on that 24' coach. I'll look up the Michelin RV tire pressure chart and link it. You'll see what I mean. The tires can be a different brand, so long as the specs match. Be sure to use "Single" info for the front and "Dual" for the rear.
