Question:

Is the RP61421 sidewinder hitch compatible with the Mor ryde pinbox RPB72-1621HD. If so can I still use the curt rail kit C16427-204 and Reese hitch RP30047

The only way you can safely tow a fifth wheel trailer with a Ram truck that has a Ram Box is with a Sidewinder pin box replacement as the pin box would no longer swing to the sides in the truck bed and hit the narrower bed rails.

Sidewinders are pin box specific so you will first need to know what pin box you have now in order to pick out the correct one.

There should be a sticker or a stamping on the OEM pin box of the trailer that will list the pin box number that is on the trailer.

Once you figure out which pin box you have you can check the FAQ I attached that has a chart that shows the correct Sidewinder to get based on which pin box you have.

For a rail kit you can use the Curt rail kit part # C16427-204 which is a custom fit and is compatible with the air suspension of your truck.

You'll want a fixed hitch to then like the Reese 16k hitch part # RP30047 and then the correct wedge to lock the hitch to the Sidewinder part # SWW-03 and you'd be set!

So, it is confirmed that the curt rail kit is compatable with the reese 16k hitch? Why not the reese rail kit?

Yes, the Curt hitch does fit into the Reese rail kit. The rail kit is made to the industry standard size and dimensions which means the Reese hitch # RP30047 will fit and work well. I mentioned the Curt kit as it fits well and has a better price than the Reese.

Yes, the Sidewinder # RP34FR that you referenced is correct replacement for your Mor/Ryde RPB72-1621HD. They both are designed for the 1621HD pin boxes. Also the Curt rail kit part # C16427-204 is compatible with the Reese hitch # RP30047 as well.

We can get your 2019 Ram 2500 short bed with RamBoxes set up with a 5th wheel hitch, and you'll need a fixed hitch instead of a slider because your 5th wheel trailer will require a Sidewinder rotating pin box. A Sidewinder moves the pivot point…

So for your set up, a 2021 Ram 2500 short bed with the RamBoxes, you will need to use a Sidewinder in order to have the clearance to tow a 5th wheel. The Goose Box doesn't move the pivot point and an offset ball just won't be enough for…

The head alone for the B&W Companion hitch #BWRVK3500 weighs about 70 pounds. Everything else weighs about 130 pounds. So the total weight of the hitch is approximately 200 pounds.

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.…

Yes, it will work. You'll just need to cut the Lance 6-pin connector out and rewire it into the etrailer Trailer Wiring 7-Way Upgrade Kit w/ Junction Box and RV Style Connector item #e99011. Here are the individual functions of that Lance 6-pin:…

Hey Tom, congrats on the new truck! Typically when we hear that someone has the OEM tow prep package they mean the puck system. This is going to be five circular holes built into the bed of your Ram truck and is by far the best way to attach a 5th…

Hey Andrew! Yes, Furrion does have a Chill Cube model with a heat pump. This was actually just released for aftermarket sale. You will need a complete system to make the switch, new R32 units aren't backwards compatible with old R410A systems.…

Since we don't carry the PullRite line I can't really speak to their quality but from what I can see from there website their 2900 model is fairly similar to the Demco Autoslide 5th Wheel Hitch w/ Slider #DM89GV. Both hitches offer 14"…
