You’re tow capacity is pretty sad and I’m unsure whether you’ll find anything light enough. Everything that goes in the Pilot has to come off that rating. But no harm in doing some research for some really light units. One option comes to mind used. Coleman made some light all-metal units back in the 70’s that might weigh in at 1000-1200# dry. They only had a stove, sink and furnace, no electronics and certainly no bathroom/shower. But they’d work fine for camping trips. The real trick would be finding one that wasn’t trashed. Good luck.
