All RV manufactures have websites with links to dealers. RV shows start in January. The straight trailers ( no slide outs) are not usually featured but you can get an idea of the quality of the manufacturer. A 26 foot bunk house would probably suit your needs. Even some of the 3500 lb trailers have small slides With your TV you will probably exceed your TOW VEHICLE gross weight before you get past 6000 lbs for the loaded trailer The 7400 lb towing capacity is with no fuel no passengers and no "stuff" and a 150 lb driver.
Look at dealer websites for used trailers and if you want a new one check the manufacturers website for the current year model
Best of luck and enjoy
