Brands of Travel Trailers

TTs generally into two catagories. Wood frame and aluminum frame. Wood frames tend to be the lower grade, often termed light weight. They will have cheaper grade cabinets, thinner seating materials, less insulation and smaller tank capacities. Aluminum framed TTs can also fit into that catagory, but generally will have larger tanks, better cabinets and furniture. There really is no "high end" in TT world. They are almost always geared more to families who tend to use them 1 or 2 weekends a month. That does not mean that any TT cannot have a long long service life. Many do. It really all boils down to how well owners take care of their RV, and not so much how much you pay for one.
As for brands I would consider if I were making a purchase today? Northwood, Nash and Arctic Fox would have to be high on my list.
