What Shock Absorbing Ball Mount Will Work With My 2016 Toyota Tundra and 2023 nuCamp TAB400 Boondock  

Updated 07/07/2026 | Published 06/23/2026

Question:

My 2016 Tundra measures 18inch at the top of the hitch receiver opening. My 2023 NuCamp Tab 400 Boondock measures 22inch at the bottom of the coupler when level. Im assuming this wont work. Any torsion or shock absorbing hitch you suggest that will work with about 400-500 lb tongue weight?

Hello Joe,

Thanks for writing in!

Based on the measurements you provided, the Gen-Y Glyder Shock Absorbing Ball Mount # 325-GH-12001 is not the right fit for your setup. Since your Tundra's receiver measures 18 inches from the ground and your TAB 400 Boondock's coupler measures 22 inches when level, you'll need a ball mount that can be used in the rise position. The Glyder is designed to be used in the drop position only.

Instead, I recommend the Gen-Y Phantom XT Adjustable 2-Ball Mount with Torsion Flex # GY52VB. This model can be used in either the rise or drop position, so it gives you the flexibility to get your trailer sitting as level as possible. It also has a tongue weight range that works well with the 400 to 500 pounds you mentioned. I attached an image of it in used on the drop side, you would need to flip it for the rise.

Another reason I like the Phantom XT is its built-in Torsion-Flex system. It helps absorb road shock and reduces the bumps and chucking that get transferred between your truck and trailer, making for a smoother towing experience.

What kind of towing issues are you looking to correct?

You have the perfect size camper in my book. Getting things geared up for the next adventure, what upcoming trip are you looking most forward to?

Thank you, Kate. I'll look into this. We tend to feel some tugging and pushing whenever the camper hits a bump or a different surface than the truck. We enjoy camping around the lower peninsula of Michigan but hope to get up north some more. Thank you for asking, and, again for your help.

@JoeL My pleasure Joe. Another option to fix what you are describing is a weight distribution hitch. Many of our neighbors won't even tow their camper without one. The Blue Ox TrackPro Weight Distribution w/ Sway Control - 7-Hole Shank - 6K GTW, 600 lbs TW # BLU36FR would be a great option just as long as your loaded tongue weight is not over 600. I attached a help article to help you figure out if it is right for you. Please let me know if you have any questions. Michigan is definitely on my list of go to places. Working here and hearing stories from our neighbors (customers) makes me want to visit every state, the bucket list is getting a little long! - Safe Travels =)

@KateF, I forgot to ask. How far down does the Gen Y Phantom XT go down from the hitch receiver? I'm worried that if it's too tall, it'll reduce my clearance.

@Joe Hey Joe, I was able to get the drawing from Gen-Y for the # GY52VB. I am going to send you separate email with it since I am not able to add pictures to comments.
