Ok, so I changed from 200 to 250 like says on the website and made the total even lower. I have B&W turn over ball and all three pieces are close to 200 lbs so that what figure I always use. Empty 5er pin weight still is 2250 how much grows loaded depends on loading and floor plan. My 5er the more added to the fridge, pantry, bathroom and bedroom the lower pin goes.
You're adding approximately 650 lbs. to the truck. You have 2,090 lbs. of payload capacity. Fifth wheels typically have 20% - 25% pin weight which gives you a maximum loaded
camper weight of 8,360 - 10,450 lbs.
