If it's the outer tire on the rear, I use my leveling blocks under the inner tire.


Very leery of doing this. Larger vehicles have a Stud with a Lug over it that tightens onto the INNER wheel. It's usually tightened with a Square Socket. Then the Outer wheel goes over that Lug then a large Nut secures the outer.

On the Ford Class C's, and I believe most other light trucks, both wheels slip over the studs then a Nut secures both wheels at once. Leaving the truck standing on one wheel, no nuts holding it, risky.

Probably won't come down, at least on level ground, but if it does, it's very likely to damage the studs and maybe the hub and wheel. I wouldn't do it.

I notice from reading pastorbilv's profile that he may to be towing an RV with an F350 dually pickup.

Jacking up the rear of a dually pickup tow vehicle to fix either an inner or outer tire in one of it's dual sets is a whole different, and easier, and less dangerous proposition (even if you leave the TT or 5'er hitched up) than trying the same on a rear corner of a Class C (or Class A) motorhome . There's way less weight on the duallies of a towing pickup than there is on the duallies of a motorhome.
