My 2 cents.
Bought a 94 Fleetwood Tioga last year, my first Driver. E350 Ford.
32 foot.
Put Firestone Transforce E range all around.
At 20 years old and OEM suspension (I believe) she dances some in the wind.
My brother had same model at one time and he swore by having the water tank half full it helped with stability. I have experimented and find this to be somewhat true. Yeah, you're carrying weight, it's a tradeoff.
Never owned a Chevy, and don't know how the Fords steer today; but my 32' Tioga dang near turns like my 94 E150 full size conversion van.
I can make a lane to lane right hand turn and I slightly encroach the other lane.
I can back this baby up into ant spot with ease.
So, after drivability, don't forget to check manuverability.
