I just talked to a tree removal company yesterday. He brings all his huge logs that won't fit the chipper back to the yard and piles them till no room, then brings in huge drum and grinds them into mulch. He told me he used to send them to a mill, but by the time he handled the logs, then paid the triaxle gas and driver, he made MAYBE a hundred bucks on the whole load every time he tried it. So... beautiful cherry, oak etc gets turned into mulch that at least he can sell and make a few bucks on. I did talk him into hauling a nice cherry log and 3 huge strait osage orange logs about 10 miles to a friends house where I can mill them.. for only a hundred bucks.
As for your loading problem... if you have a bucket truck, I would think you can finagle them into that trailer bed if they are SMALL logs only. You can always do the... jack one end up off the ground and back the trailer under that end, then shove the thing up onto the bed from the other end. I have gotten some pretty huge 7ft logs into the back of my van that way. It's time consuming though, rinky dink and and not very efficient. Rough slab them into huge cants with a csm first to lighten them, and then shove them up onto that bed.
