I've shared this in the fifth wheel forum, but thought I'd also share it for Beginners. Here is a video that I made for weighing my fifth wheel at a truck stop CAT scale.
https://www.youtube.com/watch?v=_oB68BKFB1sWeighing a fifth wheel isn't much different than weighing a travel trailer. Fifth wheels just have 2 weighings:
#1. Truck + trailer
#2. Truck only
For a travel trailer, there's a third:
#1. Truck + trailer with weight distributing hitch (WDH) engaged
#2. Truck + trailer w/o the WDH bars connected (throw them in the truck bed)
#3. Truck only
The order doesn't matter of the weighings, just that you get them each done and get the results. And you pull off of the scale to make any changes. Parking in the truck spots is the hardest part for me.. I weigh on days where there isn't much truck traffic and you can just pull through a spot.
I hope this helps someone!
