Both are good options, the LQ trailer allows you to have
the truck for running errands, going out to dinner, etc.

In my case I already had the diesel truck (F350 long bed)
and a 18 ft open car trailer so I added a 9'-10" cab over
camper. The only problem being that it is over 8' long
and that entails a HD hitch plus hitch extension that added
about $500 (used) to my expenses.

My next addition is going to be a storage box on the front
of the trailer since storage for a generator, small compressor,
floor jack, tools is very limited with the camper.
