A 33aa probably isnít a great choice for a cruiserlift. The issue is the very short 198 inch wheelbase in combination with the relatively long overhang behind the rear axle of the coach. This increases the apparent weight of the lift+motorcycle on the rear axle. Likely in the 2,000lb range. It also reduces the weight on the front tires. The 33aa isnít known as the best driving coach to begin with, so adding a large weight cantilevered off the back and reducing the traction/responsiveness of the steer tires wont make it any better.

This thread discusses adding a lift to a 33aa: https://www.irv2.com/forums/f106/hyd...aa-413187.html
Older model year 33aa had problems with being overweight on the rear axle with just normal loading of water, fuel, camping gear, etc. They typically weighed around 20K on the rear axle. For 2023 Tiffin specs show a 23K rear axle on the 33aa. If accurate, thatís a big increase from previous years. It may actually have enough axle capacity to carry a motorcycle lift without going over the rear GAWR. But Iíd still have concerns about how it might drive when loaded.
