Just couple of questions concerning numbers posted
Truck/Camper on Scales
Ft Axle 4000 (FAWR 4800) 800# left--------plenty
RR Axle 4640 (RAWR 6084) 1444# left..good wiggle room
Truck 8640 (GVWR 9200)Only 560# before reaching trucks GVWR. Passengers, stuff in truck and then all the stuff in trailer you will be over trucks GVWR. By how much???
Trailer 10200 Did you include 1880 pin weight in this number??
If you did..shouldn't. Pin weight is already added to trucks rear axle weight. This should only be trailers axle weight
Truck/Trailer 16980 This is combo total so minus truck (with pin) 8640# is 8340# which would be trailers axle weight
Pin Wt. 1880 ??? This represents a 18.4% pin weight (based on trailers total weight of 10220#) So if you add 1000# to trailer pin weight should be close to 2065#
Payload left of 560# minus increase in pin weight of 185# leaves you with 375# for passengers and stuff in truck (in bags, backpacks etc.
SO you will be very close on trucks GVWR.......OK on axle weights
Over all good match/combo.
Chucking is probably due to light pin weight %...better when % is 20% or higher
Is FW nose up/down or level when hooked up to truck?
