Thanks!
I have an additional spare for the trailer. That gives me eight total, so I can rotate out a complete set from the Jeep to the trailer/spares. Pretty handy. Plus if I take the trailer, I ultimately have up to four spares to pull from if necessary, which is just crazy. And as you note, it just looks bad-ass.
I'm planning some significant mods to the trailer over the winter, including a rebuilt frame with a new A-frame tongue and space for a box + spare on the front. That existing main bar is weak-sauce, I think it's 16 gauge box tubing. I can see flex in it now, and it's getting to the point where I am concerned it would break on me. I've heard reports of that happening to others with this particular trailer.
I've drawn up some sketches for an overland trailer. The idea being that it would be the same wheels/tires combo (which I already have 6 of) mounted onto a trailer that was just a 6.5 or 8 foot bed. The idea being that I'd have at least one spare on the truck itself and then 2 more mounted to the frontside of the trailer (to give it good tongue weight).
Kind of the same thing this tacoma trailer has going on: https://www.overlandexpo.com/compass/toyota-trd-sport-truck-bed-trailer-2020/
