Except for the engine difference, your coach is probably very much like mine. The only heat that gets into the lower bays comes from running the propane furnace. There a small vents (Black Plastic boxes with openings) that allow some of the ducted furnace heat into the area where the plumbing and tanks are located. Without that furnace running, there is no heat down below.
Front cap goes under the roof, and the curved part flexes a lot and breaks caulk often (a permanent solution is 5200 marine sealant, but it is extremely hard to remove).
Holiday Rambler's seam tape (like eternabond) is not as good as eternabond, so check if periodically. I had to recover a section on the slide top.
Be sure the front clearance lights are caulked all the way around the base (not just the top and sides).
Remove the false floor in the bath lavatory cabinet and seal the large hole left where the plumbing goes through the floor to eliminate odors from the sewage bay.
Weigh the coach (4 corner weight) and check tire capacity and set tire pressures according to tire manufacturers chart. I'd bet your left front is 600 lbs heavier than your right front. Original tires on my coach were running right at the load limit on the left front.
