What I don't underatand is roofing materials. It seams all rv roofs leak and are pretty crappy.
Q: What is the best roofing material and why?
Q: what frame design is best?
Q: is ducted a/c & heat a good choice for long-term reliability? I noticed many airstreams don't offer it, why?
What Brand/models offer all of these features? What is the price point?
Wheels...Aluminum is great, but are less durable. Aluminum will crack if impacted, steel will dent and can be hammered back into form. If planning to use the RV off the beaten path, recommend steel with hub caps that can easily change as desired.
Roofing on RV's are: Rubber, fiberglass, and metal.
-Rubber is typically EPDM and TPO. Both are very lightweight, stout and will last for a long time if cared for. Caulking the edges and opening will need repair before the surface fails. Rubber roofs can be torn by trees and such.
-Fiberglass is a premium surface and is basically bulletproof. The joints and edges must be attended to. The surface can crack if loaded (walked-on) wrong.
-Metal is almost extinct as a roof material. It can rust/corrode. It can rattle if lose between fasteners. But if cared for, it could last forever.
Framing is typically 2 types: Wood and metal.
-Wood is just like a house, but typically smaller dimension lumber. It is heavier but can be strong and affordable.
-Metal is tin or aluminum framing that is tack welded (better) or screwed together.
Comment...The corrugated metal exterior RV's will often be over wood frames.
Frame design is typically just a simple metal grid. Look for bigger materials in the frame to provide better service life.
Ducted HVAC is better for distribution. Simple 12v fans can improve that problem. Ducting requires space in the roof and floor...something some designs do not allow.
Most current brands have a wide variety of offerings. Some will have few amenities...some will offer lots.
