I’ve been planning to ditch my spare tire, I run 31s and it’s not really valid as a spare with the AWD. My original plan was to save my best 31 when I replace my tires, and make that fit. Lately, I’ve been thinking of making a tray to hold a few accessories, mainly a air compressor, small tank, and a second battery. I’d put the battery in a suitable battery box. The tire winch would be used to raise and lower it, only. I’d snug the tray up against some sort of bushing, and hold it in place with clevis pins most likely. Is this an entirely stupid idea? I’m planning on adding a large amplifier(in addition to at least 2 smaller ones for highs, and midbass speakers), I have a 1,000 watt power inverter, and I have a winch in a hitch carrier, and that a rear mount battery might be the ticket.
