Hey Rick. If you could email me directly a picture of the sticker on your pin box I'll be able to look up exactly which MORryde Cushioned 5th Wheel Pin Box like item # MR84VR you'll need. It'll say date of manufacturer, weight capacity, and have an LCI or RPO number.

If you can't email me a picture you can add all of that information into the where it says Reply to Jerred H.

Answer 1

What size tire do you have? There should be a 4 digit number on the tire after DOT. When reading the DOT number on your existing tire, you will want to look at the last four digits of the number (if there are more than 4), not necessarily the numbers…

Yes, the temperatures you mentioned are normal. If you were getting over 200 degrees that would be a bad sign. But typically if all of the hubs are the same temperature you're good and it's only really an issue if one of the hubs is hotter…

Since wheels will be able to withstand the psi rating of any of the tires that are meant to fit it you will need to look at the valve stem as that is the deciding factor. If your valve stem has the rubber all the way up to the threads, like part…

Great questions! I will answer your questions and then give a recommendation on what to do. a - The valve stem is more or less what determines the max psi rating for a wheel. So yes, there are wheels that can handle 110 psi as long as they have a…

According to my contact at TireMinders, the sensors used on the #TPMS-APP-4 TPMS system are light enough that they would have no discernible effect on the wheel's balance. I've linked to a product description video for the #TPMS-APP-4 system…

It's rather common for a camping trailer to lean to one side, it's likely the side with all your appliances and water tanks if I had to guess. In order to fix this I recommend some jounce bumpers like the SumoSprings Trailer Helper Springs,…

Answer 7

I spoke with one of the engineers at HWT and he told me that the psi rating for an HWT wheel and tire assembly is only limited by the valve stem and tire. If your current wheels or new wheels have a psi rating under 110 psi, it is okay to use tires…

I haven't heard that before so that's interesting. In the last few years, the wheel manufacturer's started removing pressure ratings on the wheels and have focused more on stating their capacity. Unless otherwise stamped on the wheel…

Answer 10

Good question, Logan. Some of the old bolt-on adapters were a problem, usually from people using the wrong size and overloading it. But 5th wheel to gooseneck adapters are generally safe and accepted as a proper and legitimate upgrade. Modern…

Answer 11

Hello Matt, sorry for the delayed response. I just heard back from Lippert and I was able to have them run the serial number. Your pin box is a 1621 which is quite common/standard. If you are looking for a replacement, the Gen-Y pin boxes are a great…

Answer 12

I spoke to my contact at Lippert and they informed me that on the Lippert 1716 Pin Box that you have, all six bolt holes per side will need to be used which means you would not be able to lower the pin box down to raise the front of the trailer. In…
