Hi all!

I have a 2012 Jayco 5er with a Mor/Ryde pin box. Is it possible to keep the pin box hooked to the truck hitch while lowering the pin box one hole by raising the trailer? The mor/ryde websie shows a PDF file where installing a pin box it is recommended to use the truck hitch. I would assume an adjustment is the same? Lastly, is this an easy job? Thanks much!

We used our pin box tripod to support the pinbox when we adjusted ours. Worked out well plus gave us the room to move around and the box was at a more comfortable level to work on. Phillip

I used the truck hitch when I removed my old pinbox and replaced with the new fifth airbourn. It work out great.

X2. I used my ceiling hoist to remove the old pin box and to set the fifth airbourn in the truck then had the DW help guide as I backed under the trailer. Worked like a charm and was a one man plus DW supervised job.
Woks good to adjust the pin box if needed.

For what it's worth: when I dropped my pin box one row of holes, I took out all but two opposing bolts at the rear, lowered the front of the pin box one hole, put in a pair 1/4 inch bolts with fender washers so that the bolts wouldn't drop out, then lowered the rear of the pin box until the holes lined up and slid in two regular bolts, then replaced the 1/4 in. bolts with regular bolts and filled in the other four regular bolts.

The diameter of the 1/4" bolts allowed for the slight mismatch in distance due to having the front of the pin box one row of holes lower than the rear holes. A pin or rod through the holes would work the same, but I didn't want to risk anything suddenly shifting and having the pin box fall to the ground when I pulled the rear bolts and the whole pin box was momentarily hanging off the 1/4" bolts.

By doing this, I could do the job alone and with truly minimal effort. It was a snap, and there was never a chance the pin box would get away from me.

Ditto on that! Exactly how we did it but used the tripod to help support the pin box. Worked great! phillip

Slarsen,

I would have never thought of that. Your method sounds very easy, I will try that. Thanks for the tip.

Glad to be of assistance. I've gained so much from this forum in the past, and to this day I get the occasional good tip from others.

added: I thought long and hard to come up with this one before starting. I was recovering from shoulder surgery (rotator cuff), and the thought of repeating it was very unappealing. And might I add, the surgery cost more than the trailer's original price! So I needed a solution that I could do practically one-handed.
