I had a pull behind tent camper many years ago, before they refined them and made them easier and quicker to put up. Mine was Trav Lite and it was ugly for sure, lol... Now I use a cargo trailer from Microlitetrailers, and carry a tent and a bunch of gear. Another manufacturer of my type of trailer is americasbesttrailers, who also make one of the best hitches for goldwings at probably the best price. The trailers are pricey tho. Lots of folks have used a small Harbour Freight style trailer and put car top cargo boxes on them. This is a much less expensive way to go and still fulfills the purpose. Others with this type of setup will probably weigh in on the benefits.
Your fuel mileage will suffer towing a trailer. The more streamlined and lighter the trailer, the less it will suffer. The best appearing tent trailers seem to come in the boxiest looking trailers, and the prettiest most streamlined trailers are also the most expensive. Time out and leisurelite both make real nice tents that are easy up, easy down, but like the Solace, come in a rectangular box. I do not know of any tent trailer that doesn't. Bushtec probably makes the nicest cargo trailer, but the wheels are very expensive if you wreck one.
That is about all I know,
