Hi Tom, welcome to FiberglassRV.
You'll need to look for an older trailer where the axle
has sagged or I'd suggest any one of the Hunter/Compact cousins. They have "pop tops" and you don't need to raise the top to use the trailer.
Be careful about buying an older trailer... one that the axle
will need to be replaced in the future. You may get it in the garage when you buy it.. but replace the axle
and it may not fit!
Something else is to watch the roof clearance... no roof A/C or cover over the vent.
Others will pop in with suggestions, I really wanted to take the opportunity to say
