Have you looked at Roadtrek's own Simplicity line? Starting MSRP for the Simplicity SRT, same length as Hymer-branded Sunlight, is about $10,000 lower. But then CW might be inflating the MSRP to make it look like the actual sale price is a huge bargain.
I don't see anything about the house systems and appliances that would call for an upgrade, for reliability. Equipment is the same grade used in most mass market RVs. I'm seeing fit and finish problems, but nothing different than what I typically find in low-price RVs of all types when I go to RV shows. If you strip everything out to upgrade it, cost may be about where it would be doing a conversion on a new van, much of the cost being labor.
