Recommended 5th Wheel Hitch and Rails For 2017 GMC Sierra 2500 Denali Duramax Diesel
Question:
Thank you for the reply. My truck is actually a 4x4....I am sorry I neglected to mention that. I don't want to struggle getting up hills or not being able to stop, etc. With some of the details I gave you how does the pin weight play into this? I just want to be sure I have the right hitch and a capable truck of pulling such a heavy 5th wheel since it's a 3/4 ton. Thanks in advance.

I wasn't concerned at all about your ability to tow a Keystone Avalanche 385BG, but I did look up your towing capacity to help you with that info. For a 5th wheel your truck will have a different rating than the bumper pull towing capacity. A truck's capacity can vary depending on the cab style, box length, axle ratio and if it is a 2WD or 4WD. Because you gave me the box length, and I assume you don't have 4WD or would have stated so, and because the duramax diesel have the same axle ratio. Your towing capacity for 5th wheel is as follows:
If you have a double cab--16,400 lbs
If you have a crew cab--15,400 lbs
If you have a standard cab--15,400 lbs
A 6-1/2 foot bed will require a sliding 5th wheel hitch. I recommend the Demco Hijacker Autoslide 5th Wheel Trailer Hitch - 18,000 lbs # DM8550034 because it does all the sliding work for you so you can simply drive and not worry about the adjustments.
If you prefer a manual slider where there is a locked position for towing and a locked position for turning clearance like around gas pumps and getting into your campsite, then I recommend the Curt A16 5th Wheel Trailer Hitch w/ R16 Slider - Dual Jaw - 16,000 lbs # C16521. This slider has interlocking jaws for great king pin connection to reduce jarring and chucking. The round tube slide rails prevent binding as well.
With either option, I recommend the Reese Quick-Install Custom Outboard Installation Kit w/ Base Rails # RP56001-53 for your base rails. I also recommend the wiring harness # 50-97-410 to put a second 7-way in the bed of your truck for easy connection access.
Let me know if you have further questions.
