Question:

I am looking to buy a reese goosebox, and do not know what model of wingset i have on my 5th wheel so i can order the correct hitch. Where do i fine this information? Also what is the difference between the 94720 and 94623 goosebox? looks like they both fit either wing sets. It appears the 94720 is bigger and heavier. I have a 41foot momentum toyhauler. 16,000 Thank you for some answers

If you check out the sticker or plate on the pin box of your trailer currently there will be a model number listed that will help us identify what pin box you have and then from there pick out the correct Goose Box. If not there is a way you can measure your pin box to determine what you have. I attached a help article that covers this.

The two Goose Box part numbers you mentioned both are for the same fit, but the # RP85FR is the updated version of the 94623. Essentially it's a beefed up version of the Goose Box with some internal upgrades as well. All around it's better.

I'd be shocked if the # RP85FR didn't fit your trailer though as it fits the very common Lippert 1621, 1621HD, and 0719 pin boxes.

I have a 5th wheel that weights 15500 lbs if I go with the 20k version is that overkill and is there a disadvantage to using that one instead of the 16k version?

Not at all. I think going with the 20K # RP85FR versus the 16K # RP94716 is a really good idea. It's not overkill (it being over-rated won't negatively affect anything) and it gives you a nice safety margin for the trailer's weight.
