Tiffin , is the manufacturer , and is thought to be one of the best as far as quality products is concerned.
B-in-L had a 2005 Allegro Bay, 35' on a Workhorse, W-22 chassis , and the only real issue he had was the coach was heavy , leaving very little , Cargo Carrying Capacity. The CCC is the weight the coach can carry , without exceeding the GVWR ( Gross Vehicle Weight Rating) and it's a number that's, required to be posted on a weight sticker, that can be on a cupboard door or in a closet somewhere in the coach.
You have to be aware of the CCC on any unit you consider , and many older RV's didn't have much capacity and were easy to overload, leading to handling and other issues.
