My F150 has the factory brake controller. 1,200/12,000 WD hitch is ordered and should be here next week and the trailer in a couple of weeks. I'll weigh everything once it comes in and see if the 500lb figure is accurate or not. I know the 20' 7k trailer is right at about 2,000lbs but it wouldn't surprise me if the 10k is closer to 2,700 or so with having heavier axles and an inch wider metal which with tractor, FEL loader, and 5' cutter would be about 8k total. I did get the wood floor so that'll help a little with the weight. mainly just worried about tonque weight which having two more feet with the 20' trailer (vs 18' I've used in the past) should help a lot and the WD hitch more so. Weighed the truck yesterday with myself, full fuel tank, and usual gear in the bed and it was 6,020lbs so still have 1,000lbs of head space for tonque weight assuming I don't exceed any axle limits.
