A 13 footer is an easy tow for either a recent Cherokee or a vintage Scout.
There have been a lot of 13' FG trailers built over the years. Boler
started it all and a vintage Boler
is not rare. These are all quite vintage now, and may be more work than you desire. Casita
both build 13' models and they're roughly comparable depending on the options the trailer was built with.
Other trailers you might run across are UHaul
CT-13s, Burros, and the smaller Trilliums. All are now 'vintage' trailers, but younger than the Bolers. This group of trailers all have many happy owners and there's a fairly broad base of owner knowledge and experience. There are some neat design features in the Trilliums in particular - I recommend you look them over before you decide you must have a 13' Scamp
