I have a Dutchmen 190QB (bought new, built 10/2013) with the fiberglass siding and is basically the same trailer as the 201QB. In the last two years I've replace both LP tank hoses, the sail switch on the furnace, two drawer latches and most recently the shower faucet. No issues with the siding or the frame. It a great size for two people and easy to tow. IIRC it weighed in with full fresh water and gear around 5200 pounds.
The drawers sides are plywood, the drawer fronts & cabinets doors are wood but I think the cabinet frames a MDF. No issues to date with their construction (no warping or sagging).
I'm still a happy camper and this is my second Dutchmen; previous was a Freedom Spirit made by Dutchmen. With that said, Dutchmen is considered low end but in truth all brands are made cheap. You could pay more for other brands that look nicer but aren't really built significantly better.
Find a layout that works for you and get out there camping.
