Rozinbag, how about something like this
Geo Pro G19FBS?
The website claims an unloaded vehicle weight of 2962# so I’d think a loaded and ready to camp weight of a little over 3600#.
If you could live with downsizing that much, check around here and some Rockwood dealers to see if you can determine what it would really weigh. Figure on 600-700# above the weight on the sticker on the side of the trailer.
