Upgrade Pin Box To Minimize Chucking

Question

Question:

Hello, I have a question regarding the Morryde RPB72-221002300-03 vs the Reese Airborne 5AB-E7920. My 5th wheel has a GVWR of 9000lbs, towing with a 2019 Ram 1500 tow rating of 11240lbs, using the Anderson Ultimate Hitch. We are new to the 5th wheel but the chucking is somewhat unnerving and constantly trying to adjust to minimize the chucking is tiring. looking for opinions on the 2 products to minimalize the chucking.

It is important to first say, chucking can be reduced or minimized, but never totally eliminated. Upgrading from a standard pin box to one of your choices will be a dramatic improvement. I also think the additional connection created by the Andersen hitch does not help, but that is what you have either way.

The MORryde # MR85VR is a "cushioned" pin box that uses a thick rubber pad that will flex mostly front to back and side to side.

The Reese 5AB-E7920 is an "air-cushioned" pin box that also has a shock absorber, however it has been discontinued.

The models you selected work with many flange bolt patterns including the Leland 7920 and 7921. If you have a different bolt pattern just email me for an updated recommendation.

Answer 1

As I can not say for certain why there is not a Reese Goose Box that fits the Leland 7920 on your 2003 Jayco Quest, it is most likely due to no one making 5th wheel campers with a Leland 7920 pin box anymore. Since Lippert has taken over the majority…

You will have to go with a sliding hitch to allow the trailer to make tight turns. For a trailer 8 feet wide the only bed length that's going to allow 90 degree turns without a slider is a stationary hitch. That being said you have two options.…

The OEM prep package consists of 4 "pucks" in the bed of the truck that will allow you to drop in puck style hitches for easy installation and removal, that gives you a completely clear bed when not in use. The B&W Companion OEM 5th…

I took a look at the Gen-Y Hitch Shock Absorbing 5th Wheel Pin Box #325-GH-8040 that you mentioned and it's actually going to be a fit for the Lippert 1621 and 1621 HD 5th-wheel pin boxes, and not your Leand 7920, however I do have another…

If you plan on always having same air pressure in both bags I would also go with a union tee like the #AL21838 which will allow you to have both bags at same pressure with a single inflation valve. Otherwise the kit does not come with this so…

Answer 6

Chucking usually occurs while accelerating and decelerating, but if this is happening while regular driving, there is something else going on. As you are using the B&W Turnoverball #BWGNRK1012 to tow a fifth wheel camper, I assume you are using…

The B and W Turnoverball hitches like #BWRVK3400 have an adjustment built into them to allow for varying height truck bed. If you check out the picture I attached you'll see that the socket post is adjustable to allow it to fit your setup. This…

The Lippert/Trailair pin box that fits the Leland 7920 is #UF35-946208.

Answer 9

Since your 2021 Ram 2500 has the 6-1/2' bed the B&W Companion Gooseneck-to-5th Wheel Hitch Adapter #BWRVK3500 will more than likely not allow you a full 90 degree turning radius. With that said it can be sometimes made to work if the trailer…

Answer 10

Your extended pin box doesn't actually give you 10 more inches of offset since when the trailer turns the pin box swivels which puts the trailer the same distance from the truck cab. The only time you can use an offset's distance in the…
