Maybe I am overlooking a few things, but here is what I found out about the Open Range and some of the issues brought to light so far...
Quickly scanning the website I see six lug 16" wheels, top of the line fifth wheels have eight lug wheels to carry the weight.
I notice on the spec page they list tires as 16". What size are they and whey don't they list the size?
I have attached a picture of the 8 lug 16" wheels... can't see the tire size but can see that they are an ST.
I could have missed it but I saw no mention of contruction methods, insulation, or R values. Aluminum framing is light in weight and won't rot in the case of a water leak but when trailer frames flex, as all of them do, aluminum joints and welds crack. Aluminum is typically used in side walls but I've never seen it used in floors. A glance suggested aluminum framing in walls, floors, end caps, and roof.
The website states "Four-Season Protection Package standard - up to R-39* Roof, R-38* Floor, R-9 Sidewalls - Included". I see they say "Up To" so I am sure that is not the R values for those entire areas. Double Pane windows are an option I would spec so maybe the trailer will have a decent overall insulation package for the price.
Here are a few other items concerning their construction that I noted and wouldn't mind some input on:
