Welcome to the forum. I like your train of thought but you may be looking at several obstacles. First, I think you will be over your payload on a Tundra. Sorry Tundra folks, I don't mean it personally. Most trailers are @ 96" wide on the outside, which will leave you with more like 92" interior. Are you really skinny?? I think you may want to look at a used motor home and a dolly, or have someone drive the Jetta for you. If you find a way to fit it into the 5er toy hauler, watch carefully your weight capacities. Seems like your TV need is more in the 3/4 ton range to me. Good Luck!!!
