Yes it’s a truck tag. I transferred a specialty plate to the Gladiator when I bought it and they gave me a truck sticker for the front window bc it wasn’t listed on tag. Transferred from a Grand Cherokee
Yes I would recommend it, works great. You just need the wiring harness 3014p for Tekonsha and it’s plug and tow. Connection is up under dash over area where dead pedal should be.
You may have the wrong wiring harness. The one pictured is the one I got for Jeep. I got one error initially when I hooked it up and used the manual brake function on brake controller. Trailer was not hooked up at that time, so I shut down the truck and restarted w no errors since then.
It’s 23’ long and 8’ wide. Mirrors were not too bad because they are taller than many normal ones. I used add on mirrors w/ my Grand Cherokee, haven’t tried that w/ the Gladiator.
