My calculation has you looking at trailers that have a DRY weight no higher than 2400lbs.
1352 - 400 - 450 - 50 = 452 (payload left for trailer tongue weight)
452 / .13 = 3477 (max weight of trailer)
3477 - 1000 = 2477 (dry weight of trailer assuming you only put 1000lbs of water and stuff into it)
I pack about 1500lbs into mine for a month long trip and only about 10gal of water while towing.
I understand you have a budget constraint. But I would only consider a 4 season like Arctic Fox or similar to a Northwoods trailer with thermal pane windows for fultiming along with a heavier duty truck with lots of payload. (I think I just described my retirement rig :)
