I’m with the sell and buy a boat with A/C group. There’s a lot of nice late 80’s 270’s and 300’s out there. A/C seems to be far more common in the 300’s.
Also, since OP is relocating I would imagine unloading a boat without AC down south is going to be a tough task and probably lose more money. If it's in the cards, sell the boat before you relocate and buy one with AC once you're settled into town.
