Agree w above. Long trailers are easy to tow and easier to back up.
DOn't buy based on a fear of having to learn a new trick. Lots of not-so-smart drivers on this forum can do it so can you.
Get the smallest trailer you can. Bigger not always better. Lots of downsides to a big roomy camper too. A lot depends if you plan to drive it, or just park it mostly. SHort trips to a close campground are easy. Long trips to new destinations every night are easier with the minimal caper. things to think about.
Youre camping! Some concessions can be made by anyone. It is not your house.
