Hi Jon!

Since you're installing stabilizers on the rear of a Class C, my recommendation would be the Ultra Fab Power Twin 2, part # UF39-941704, if your main goal is making the coach feel as solid as possible once you're parked. The Trailer Valet Drill Powered Stabilizer, part # TV68FR, is an excellent option too, especially if convenience and quick setup are higher on your priority list, but personally I'd go with the Ultra Fab for the added stability.

The Trailer Valet uses a cordless drill to quickly raise and lower the legs, so setup is fast and easy without having to crank by hand. Since each leg adjusts independently, it's also a little easier to work with if you're parked on uneven ground. It has a compact design that tucks up close to the frame, which helps maximize ground clearance.

The Ultra Fab Power Twin 2 uses a traditional hand crank and features a cross frame design that ties both sides together. That wider footprint does an excellent job of reducing movement, especially the side to side rocking you can sometimes feel when people are walking around inside the RV. It also offers up to 30 inches of lift, making it a great choice for taller motorhomes.

If you want the best of both worlds, I'd skip the manual version altogether and go with the Ultra Fab Power Twin II Electric Stabilizer with Dual Motors, part # UF39-941705. It gives you the same solid cross frame stability as the manual model, but replaces the hand crank with dual 12 volt motors, so deployment is as simple as pressing a button. For a Class C, that's the setup I'd choose without hesitation.

Out of curiosity, what Class C do you have, and are you mainly looking to cut down on side to side rocking or just make setup at the campsite quicker?
