Welcome John, there are lots of us camping in small fiberglass
trailers who like you have moved up from tent camping.
There is a great thread on this forum called Trailer Weights in the Real World
that you should take a look at to see what ones really do come in under 2000lbs once loaded with gear.
I am assuming the weights you are quoting for the Casita and Scamps have come from the manufactures websites and they are what we call "dry weights" and unfortunately they dont include the weight
of any optional equipment such as a propane
, stove, fridge
and awnings etc. and they sure dont include your own belongings. A good rule of thumb to use when looking at trailer manufactures dry weight
is to add about 600lbs in order to come up with a weight that may be more realistic once hitched up. Unfortunately a Scamp 16' under 2000lbs for example isnt something you are going to find. You are probable going to need to look at trailers 14' and under - but lots of chooses out there in that regard: Scamp 13', Burro
13', Hunter Compact Jr, uHaul
and a Boler
13' to name a few.
