We have a 27'Winnebago Vista and like others are not satisfied with the handling. In a recent Motor Home magazine article they detailed the upgrades to a larger coach by Henderson that was interesting...

Before I would spend any money on bolt-ons I would do the basics first. In other words load the coach exactly as it is when you travel with full fuel and fresh water(if you fill your tanks for travel), as well as food and clothing. Then have ALL four corner weighed and adjust your tire pressure according to the manufacturer's specs. The next would be to take it to an alignment shop, while the coach is still loaded for travel, that can deal with motor homes and get a front and rear axle alignment or a thrust angle alignment. Some shops will tell you that your rear axle is not adjustable when they DO NOT have the equipment available to set the trust angle on an RV chassis. It can be adjusted.
After you have done these things, and you still are not happy with the way the coach drives, then try some add-ons, one at a time.
Tell us how you adjust the rear thrust angle on a gas chassis with no provisions for adjustment? The spring hangers are bolted to holes in the frame, the spring draw bolt head aligns with a hole in the axle tube. There are no cams, no adjustable rods, etc.

The rear axle is attached to the springs with U-bolts that can be loosened to allow the axle to be moved as necessary to get it in to perfect alignment. You don't move the springs but the rear axle itself can be moved. Here is a link to Brazels which gives some details on the services they offer. There are other alignment shops that have the ability to give a gas or a diesel pusher RV a 4 wheel alignment. Brazels 4 wheel alignment on a gas chassis
Here is another link: FMCA alignment
Here is another place that can do the alignment as can any shop that has Hunter equipment designed for thrust angle alignment: Hendersons
Another place: Sunshine Service
No! The rear axle is located on the springs with pins. If the axle can be moved then it is unsafe and shouldn’t be driven. Axles need the pins to properly locate the axle. Other wise it would move on the spring under acceleration or braking. And the u bolts are not strong enough to keep it from moving.
