I know you didn't ask this but when I was researching my options somebody mentioned that I might consider buying a used truck or full size van and dedicate it to the job of towing. Then keep your gas sipper as a daily driver.
That might not work for your situation but I thought I'd mention it.
In my case we just decided to bite the bullet get the camper we wanted and then went out and found a truck that could haul it.
We did not want to get into a situation where we got a camper that "fit" our TV, end up unhappy with it, have to trade up to a larger camper *and* a new TV... And also take the associated hit on depreciation - since we were only looking at new campers.
Best of luck.
