There are no specific fits for a 2013 Freightliner M2 for a hitch or wiring, so your best option is a weld-on hitch. If your frame is up to 44 inches you can use the Draw-Tite Ultra Frame Service Body Trailer Hitch Receiver # 41990-16 for 16 inch tall brackets or Draw-Tite Ultra Frame Service Body Trailer Hitch Receiver # 41990-07 for 7 inch tall brackets.

Then for a 7-way you will need to hardwire in the Vehicle Wiring Harness # C59236 with the Universal Installation Kit for Trailer Brake Controller # ETBC7. You will also need some extra wire which you can get with part # 10-2-1.

I have added links to instructions and video reviews for you as well.

I think you are going in the right direction. I would definitely replace the 14 gauge wire going to the trailer brake magnets with 10 gauge wire or larger. Usually larger than 10 gauge is hard to get into the trailer connector though. I would also…

It really does sound like you have a Dexter 3,500 lb axle. The brake assembly that would work for you is the part #23-26 for the left hand side and part #23-27 for the right hand side.

Hey Joe, yes the Lippert stabilizer jack part #LC298707 does fit your Grand Design Transcend 245RL but it is sold individually so if you wanted a set for the front and the rear you would need to order a quantity of two.

If you just need a 4-pin to 7-pin trailer wiring adapter, then you can use part #C57672. This will plug into the 4-pin trailer connector on your brother's vehicle and give him the 7-pin socket for the trailer. Keep in mind, this will only give…
