I have a modified M100 trailer I use with this and it works perfect and looks OEM. Trust me, this is the way to go.
Can you post pic? I haven't mounted mine yet and you have me curious.

What's that bad boy weigh? And how does it tow? I currently tow my Fleetwood Graphite (2700 GVWR) with a Nissan Titan. It's kind of overkill . . . .

unloaded weight is 3015 lbs. GVWR is 4,800 lbs. Tows great. I know I am pushing limits but manual trans and 5:13 gears help. Just took 1500 mile trip to Tenneesee mountains and it did well. a couple long 7% grade hills had me down to third gear but was able to maintain 40mph. Looking to add some umph this year by adding Ripp SC

Seen this done before and didn't like it for one reason; it gets in the way when trying to access the tailgate with the trailer hooked up. Also don't like running heavy power wiring so close to the fuel filler. I mounted my setup on the bumper, just built a little box for it out of 1/8" sheet. So far it's never been in the way; is very well protected and no worries with wiring so close to fuel.

I put a thread up a few months ago about wanting to do it on mine and it was pretty easy, having a car hoist to able to use made the job much easier then crawling around underneath it because i tried it that was and gave up lol

This is a very interesting way to mod. I am interested in doing this as my first mod followed by a 2.5" lift. What measures did you take to protect the metal once you drilled the holes? How is it fastened on, additional drilling for the bolts I would assume? Did you take precautions to safe guard against water, any sealing, rubber gaskets or silicone?

No need to seal anything, it is all exposed in there anyway, it doesn't change anything. Its one large bore hole in the middle, then once you have that and insert the adapter in there then you mark the other 4 smaller holes and drill them. After all the holes are drilled you can just dab some paint to cover the metal. It won't rust out in your life time. Its really easy and the best mod I have ever done. We have done this to a half dozen Jeeps and no problems.

The extra pins on a 7-pin connector provide:

a). Trailer brake control.
b). Reverse lights on the trailer.
c). A "hot" wire to charge the battery on the trailer.

You don't get that simply by using a 4 to 7 pin converter.

....then it seems rather strange that you would need a 7-pin connector converter. Generally, any trailer that has a 7 pin connector has one because it has trailer brakes. If you're just pulling trailers that have a 7 pin connector on them when they could be using a 4-pin connector...that would just be rather strange.

Quite a few trailers I have pulled have the 7 pin and no trailer brakes. They were U-Haul and car dolly trailers. You know as well as I that it's a crap shoot on most of those types. I just finished building a quad trailer for a friend. We put a 4 pin on it. Went up to the trailer sales and looked at similar 5x8 trailers. No 2 were alike is a lot of 6. And 2 had 7 pin connectors. Sales guy was useless. I asked him about it and I might as well said it in Latin.
