Winnebago Sunstar 31be driving impressions

Not specific to your model but on the F53 there are lots of things that can affect handling that are free or nearly free to straighten out. MH's are never set up properly at the dealership. First thing would be to load it for travel (people, fuel, water, food etc) and weigh it. Then set the tires PSI accordingly. Incorrect PSI is one of the number one reasons for bad handling. After driving it you could determine if you want to do the cheap handling fix. Lots of posts on here about it, and again, that's free and will make a remarkable difference in handling, wander and truck push.
