Hello Roger,

Thanks for reaching out! Unfortunately, I don't have a database that tells me exactly which leveling or stabilizer systems will fit every motorhome. It would be pretty sweet if a list like that existed, but with RVs there are often differences in frame layouts, tanks, plumbing, wiring, and other components that affect what can be installed.

If your goal is simply to add electric support at the rear of the coach to reduce movement when parked, the first thing I'd look at is the Ultra-Fab Power Twin II Electric Stabilizer with Dual Motors - 30" Lift - 6,000 lbs # UF39-941705. This stabilizer is designed to fit frame widths between 48" and 80", so you'll want to measure the distance between the frame rails where you'd like to mount it. You'll also want to make sure there is enough open space for the unit and that there are no tanks, plumbing, wiring, or other components that would interfere with installation.

One thing to keep in mind is that the # UF39-941705 is a stabilizer system, not a leveling system. It is designed to reduce rocking and movement while parked, but it is not intended to lift and level the motorhome.

If you're looking for a true electric leveling system, or if you'd like me to check for other options, I'd be happy to help. If you can provide the frame width where you'd like to mount the jacks along with a few photos of the rear frame area, I can take a closer look. Pictures showing the frame rails, any existing jacks, and the space available for mounting are especially helpful.

You can send photos by replying directly to the email you'll receive after this response, and I'll be happy to see what options may work best for your Thor.

What do you currently have on there, manual scissor jacks?
