Question:
Found out I need to get a Superhitch Max for my truck, due to my camper being a down style. How long of a Supertruss would I need to install to pull a Big Tex 60PI behind a Wolf Creek 910 camper with a Fox landing step? Do I measure just to the bumper of the camper, or do I need to include the fold up Fox Landing step too in determining length.

Hey Richard, welcome back. I don't have specific measurements like that but looking at the pictures of a Wolf Creek 910 camper with a Fox landing step installed, I'm thinking the 36" item # TLE1536 is going to be the minimum extension you'll need but I wouldn't rule out needing the 48" one either.
The TorkLift SuperHitch Magnum Trailer Hitch item # TL74FR is going to be the correct one for your 2025 GMC Sierra 2500. The hitch pin holes sit right at 2" behind the farthest edge of your rear bumper. What you can do is take a measurement from the end of your bumper and see how far out that step sits folded up. That'll give you a pretty good idea of how long of an extension you're going to need to pull your Big Tex 60PI trailer with your camper loaded up.
You're also going to need to extend your Sierra's 7-Way connector. Both Supertruss extensions come with 7-way wiring brackets but not the longer cables. I have listed the 7-way extenders you will need to do this below.
36" Extension 7-Way item # TLW6036
48" Extension 7-Way item # TLW6048
How heavy is your Big Tex trailer when you're all loaded up?

What helped me deciding length for the extension was to load the camper and back up to my trailers and look at clearance, obstacles , and what ever I purchase in the future would work. The steps and gaining access to the camper were not going to fold out but I still had a way to get in when loaded. Does the trailer have enough turning radius, Measure out from vehicle receiver to ball hitch when feeling comfortable everything will work fine.
