B-in-L had a 35', 05 Allegro Bay,8.1, and it was ok for power, he did a cross continent tour with his.
Things to watch for , very low CCC ( Cargo Carrying Capacity ) the W-22 chassis under those coaches 35 & 37 ft. was nearly overloaded from the factory and he was always loaded to the GVWR when traveling.
There is lots of room to carry your stuff , but no weight capacity to handle the load.
Brake recall, there have been 2 on that chassis.
For a Class A of that length you should look for a minimum of 2500 lbs CCC.
If memory serves ( he sold 3 years ago ) his was 1200.
Check the weight sticker, usually in the back of a cupboard or closet, like the picture below.
