Good luck on figuring out the best way.
I did own several coaches, that even build on commercial chassis have been "stretched"
When you buy 40' DP that was build on chassis design for 34' bus, you WILL have problems.
So 12 years ago I bought 30 years old Prevost conversion. It was rotten inside, so did full interior remodeling, but on the engine replaced one seal, valve cover gaskets, radiator clutch and some hoses. Than new brake system diaphragms.
Did not put too many miles, but brakes should be good for another 200 years at present rate.
I DIY what is my fortunate and in 12 years I spend less than $2000 on chassis maintenance and parts.
Try to beat that with so-called "Cheap" brands.
