Yes, you can Bill and thanks for the picture. You'll be able to install the Reese 5th Airborne Premium item # RP78FR on a Lippert 1116 pin box by adding the Spacer Kit for Reese 20K 5th Airborne 5th Wheel King Pin item # RP97FR. This set up will give you a 20,000 lbs capacity and bolt right on to your 5th wheel trailer.

Great. I had a fifth airborne side winder on a short bed truck, and loved it. Now I have a long bed. And I want to stick to what works !! I’ll be ordering soon. Thanks for the quick reply.

@Bill I totally get it Bill! It's pretty hard to move away from something you know works that you're comfortable using. What kind of trailer do you have and how long were you using the Airbourne Sidewinder?

@JerredH I have a 2018 Montana High Country 344RL now. I used the airborne sidewinder for about 5 years on a short bed Silverado. (I still have it). But I got a new truck a few years back, and I got an 8 foot bed. So I don’t need the sidewinder part of it. It made a world of difference towing. (2 different fifth wheels) I bought it when Cequint owned it. Before Reese.

@Bill Yeah I bet that really helped. Those rotating pin boxes make towing with a short bed truck a lot easier.
