The Escape manufacturer.... Reace and his wife Tammy are members here on FiberglassRV. Nice, approachable people. I'd like to think the Escape 5th wheel was built to specifications based on input from the members of FiberglassRV.
All I can tell you, is I'm impressed with all the Escape trailers and there's an Escape 5th wheel in my future. It doesn't matter one whit to me how many they've built. Everything other than the frame and body are made by other manufacturers... refer, furnace
, A/C, windows
, etc. Reace and Tammy are first rate when it comes to customer service... just ask anyone that has either ordered a new trailer, or SOB (some other brand) and wants Escape to help with mods or repairs.
But, if you want definitive answers to your questions, you'll need to contact them directly.
