In order to find out which towbar and d-ring adapter will work with the Fab Fours Grumper Bumper on your 2011 Jeep Wrangler you will need to take two measurements, the thickness of the d-rings and the diameter of the pin hole. I was not able to locate this information on Fab Fours site which is why you will need to measure this for yourself.

If they measure to be 3/4" thick with a either a 7/8" or 1" diameter pin hole then you can use the Adapter for Jeep D-Ring Bumper Mounts part # RM-035 but if they measure to be 1" thick with a either a 7/8" or 1" diameter pin hole then you can use the Adapter for Jeep D-Ring Bumper Mounts part # RM-035-1. There are other Fab Fours bumpers that use the 3/4" thick d-ring so I believe it should be correct for you as well.

These d-ring adapters can then be used with the following tow bars:

Falcon 2: part # RM-520
Nighthawk All-Terrain: part # RM-676
Falcon All-Terrain: part # RM-522
Sterling All-Terrain: part # RM-576
BlackHawk 2 All-Terrain: part # RM-422

I really like the Falcon All-Terrain part # RM-522 because you get a lot of great features for a reasonable price. I have attached a review video for you. I would also recommend checking with the manufacturer to make sure the bumper can be flat-towed.

For starters, we do not recommend triple towing with your motorhome nor are our products designed to do so. Also, in some states it is illegal so you will need to check this beforehand as well. The issue is going to come down to powering the trailer lights because the owner's manual for your 2011 Jeep Wrangler requires that the battery be disconnected. In order to power the Jeep tail lights I recommend using the Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit part # RM-15267. This kit is very popular for Jeep owner's and we even have an install video on a similar 2014 model which I have attached for you. Unfortunately, I don't have any solutions for you to then power the trailer lights as the power would need to come from the motorhome (battery disconnected on Jeep) and the tail light circuit on the motorhome would need to be rated for the power draw of both the Jeep and trailer lights which is a lot to ask.
