Why not do a light trailer? It probably would have been way cheaper than the towbar setup assuming you have the brakes etc all plumbed in.
Way cheaper to use my car hauler, for sure.
I bought the Mopar harness that bypasses the Jeep trying to run the lights... uses relays... and charges the battery, which only half-assedly works (it highly depends on the +12v from the towing vehicle to tell it to ignore the Jeep systems, so if you have a good battery in the Jeep and the towing vehicle drifts low like they do with a modern ECM/voltage regulator, it sometimes switches to the Jeep controlling the lights). That was $150 off fleabay. Not sure I'd pay $400 for one. It's great when it works right, but sometimes the relays trip off which causes the brake lights not to be that bright. Would be so much easier to use a switch and cut the harness.
$50 for a decent 7 to 6 umbilical and 6 pin receptacle to mount on the front of the Jeep from the Shamazon.
$300 for Maximus 3 tow loops.
$110 for Roadmaster tow bar adapters to the Maximus 3 tow loops.
$300 for a used Demco Excalibar3. Like $1k otherwise. Still looking for another Roadmaster Sterling All Terrain but the Excalibar is fine, just heavy as fuck. The Sterling All Terrain is super light, I gave mine to my Dad for the TJ.
$1300 for a Blue Ox Patriot 3 2022 model (has the semi-modern wireless control panel).
$130 for a Tuffy under seat drawer so the Patriot3 had something solid to push on instead of the seat.
The difference is that I can drop the toad in two minutes and connect it in 3 minutes. I leave the tow bar on the motorhome and the only thing I have to mess around on the Jeep is to pull out the Patriot 3.
If we were fulltiming it, I'd probably build a purpose built single axle T-trailer for the Jeep. Extendable tongue. That way I can collapse it down and get it out of the way. Some of the campsites we have been on are a struggle to fit the motorhome and Jeep on.
