This is exactly the same system I have. 1/2 ton crew cab with heavy-duty rear springs + 7000 GTWR trailer with 16' closed-side box and ramp. Way easier picking up 12' or 16' lumber in that trailer, than in any pickup, even a "long bed". Plus, I use the trailer for hauling firewood, and mounted a winch on the front for fast retrieval of logs, rather than heaving rounds into a stupid pickup bed. I haul maybe 10 loads of logs per winter, from various sites to my house.
Trailer is also a great way to move your tractor, either for work or repair.
I probably should run a weight-distributing hitch, but so far haven't bothered, as all my heavier hauling is real local.
