An 11 year old chassis with only 10k miles, which means it sat alot. My first thought would be a sticky brake caliper.

Are the tires original? If yes, they might be delaminating. Most RV tires age out before they wear out.

I ripped the tread off my passenger-side rear tires. Smoked them good. When I had my brakes done, the mechanic said the passenger-side emergency brake had been disconnected. He re-connected it.

Found out why it had been disconnected - it was not releasing even though the parking brake had been released up front.

As a result, I guess, all the power went to the driver-side wheels, while the passenger side rear wheels dragged. Wore the tread right down to the cords. Fortunately the tires were about to age out and I was due for new tires anyway.

I would take it on a 20 mile ride then pull into a parking lot and shoot each tire and rotor with an IR gun from HF ($19 with a coupon if you don't have one) if you find that one of the rears are much hotter than the front ones your rear brakes are dragging or sticking. If so clean and lube the caliper. If you never had the brake fluid changed now would be a good time to do that also.

Can that be done without jacking up the RV?

Yes, a very simple test.

DO NOT DO THIS! /\

You have a problem that needs to be identified and repaired.

The flex hoses in the brakes could also be causing problems.

On a MH that is 11 years old and sat a lot it is more likely a sticking brake caliper. The test will identify which brake is dragging by the heat buildup,and which one needs repair. The OP can then see after calipers are cleaned and lubed if brakes retract and if any other repair is needed. It could also be the rubber cup inside the piston. Rubber flex hoses can swell causing a restriction of fluid and piston to retract more slowly. Cleaning the calipers should be general maintenance on a MH especially one that sits for months at a time.
