My motorhome has the same chassis. 36' Ford 460 w/tag axle.
Once I took care of a couple issues I feel it is good platform.
The factory exhaust is very restrictive and prone to manifold leaks. Headers and a low restriction exhaust really woke up the power level.
The brakes needed to be completely gone thru and the tag axle brakes required some real detective work to locate parts but now they work well too.
There are several of us here that have experience with these chassis and can help with any issues you may encounter.
Best of luck with the Bounder.
