Just how full is your 6x10 trailer? And what is the size of the wood in it?
Myself, I've cut 6" locust, measured/cut to length at 80" and 60" to fill my short box F250 32" tall, and a 6x12 dump trailer to 32" tall. That includes the felling, measuring, bucking, carrying logs to truck/trailer, loading so they fill in tightly, lunch/saw breaks, and was home 7hrs from when I left, feeling beat. It was 70* and most of the work was in full sun, too hot, but sometimes that's just the way it goes.
My most fun, and productive day, was using a landowners little compact 4x4 tractor to transport my bucked rounds to the truck. After 3hrs my 80"x60"x42" truck bed was full with oak/cherry avg 12"dia. Again, lunch/saw breaks included.
On this occasion, being less weary than usual, I did split off the tailgate and stack right away, comes out to one cord+ in the end.
