Currently own a '73 Boler (13foot) but it's up for sale. Want to move up to a 16' Scamp with side dinette, so that if it's really really crappy outside, we can sit and play cards, eat, etc. and still have the bed made up. When we camp, we spend 95% of our time outside as we have a screen room which protects from rain and mosquitos if they're bad. Usually put the screen room over the picnic table so we can eat outside even when it's raining. If the weather is good and not a lot of bugs, we're in camp chairs reading, playing cards, or out hiking. To me, the trailer is a hard shell tent. It's for sleeping and changing clothes and that's about it. Don't need to be watching TV, sitting in the trailer reading, etc. Camping is outdoors time!
For those of you looking to move up from a tent but don't want to haul something big, I strongly recommend a fibreglass trailer of some sorts. The used market for FG trailers is pretty good, but good ones go fast.
As far as weight, Bolers can start at as little as 800lbs for the basic model with the ice box and go up from there, depending on the features or on the previous owner's customizations. Other brands are Trillium, Escape, Scamp, Bigfoot. I pull my 13foot Boler with a v6 Tribute without any issues. I have a fridge, 2x12v sealed marine batteries, and solar. I'd guess dry I'm at about 12-1300lbs. Also, there's a good chunk of FG trailers that are lighter than tent trailers.
Keep an eye on Kijiji. Also, these two sites are excellent resources for buying and/or owning FG trailers:
