I know your frustration. Just like purchasing a new vehicle. To get a few very useful options we want, we had to select the top tier packages with all the bells and whistles, some of which we will never use.
Now for TTs, the manufactures seem to think people like my wife and I that want a trailer no longer than 26'or 27' also don't want the luxury trim and upgraded upholstery they only offer in their much longer trailers. Naturally I'm not talking larger appliances and furniture, just a little more upscale furnishings.
