You mentioned you looked at "pop ups" so I just wanted to clarify the hard sided ones differ from tent trailers because they don't have any canvas sides.
A-Frames are easy to put up and take down (pops up/down in a minute or two, or less!) They have a stove, fridge, furnace, A/C, microwave and more. Sleeps anywhere from 2-4, weighs 1800-2200, depending on model. The cool thing besides all that is that with the low profile, there is barely a dent (if any) in my gas usage when towing...depends what I loaded on the deck.
Also might help others to know what your trailer needs are (besides light weight)? What are the necessary amenities you want the trailer to have?
