Talk of floor rot got me worried, so I checked on that. None to speak of. Glad I bought a Jeep that was driven out in the desert/valley.
Removed the old class II hitch. Hoping to sell it on CL but doesn't seem like anyone wants to buy a class II (except the government agency that owned the Jeep before me).
Painted the new class III hitch and installed it. Holy crap was that a hassle. Bumper and skid plate both had to be pulled out just to get the hitch in. I touched up a few things with the same matte black rustoleum as the hitch and then got it all back on before dusk.
Next up: buy hitch receiver covers, pull all rear seat components and seatbelts, build a sleeping platform in the cargo area.
