You must be towing with a pretty small car
There aren't many trucks with tires as small as a 10' trailer's!
When I need a trailer, I need a big one, so I'd try to find something 16'ish in size, or bigger. 20' or 24' would be nice sometimes. If you're going to get a trailer, get one that can do everything you need
If you just need a "pickup bed" than a 10' would be fine. If you need to haul something bigger then get bigger; its usually less than $100 per extra foot of length. Rarely do you find yourself "overtrailered". I wish I had purchased a 24' trailer instead of the 16' + 4' trailer I ended up buying back in Febuary.
