Unless you are in "specialty" market doing campfire wood for $$ (or cooking wood, etc), 100 cords a year won't keep you afloat, and certainly won't be enough to afford a 30-40k truck.
I'm not trying to be a debbie downer, but I just want to give truthful info.
I do 500-600 cords a year of firewood, plus tree length, plus some small engine repairs, welding, machining, land clearing/dirt work, etc and I'm certainly not rolling around in the money. Staying afloat fine yes, but it doesn't take but a string of back luck to but a hurt. Figure a skidder engine... easily 12-15 grand, some of the hydraulic hoses on the delimber are $1500+, etc.
Don't epect to be profitable with a chainsaw and splitter. You will work yourself to death. My first year that is what I did. Now with machinery what I do in a day would take me a week by hand.
Do you already have the logging equipment and a processor? If so, great, you have a real good start. If not... it's going to be rough for a while and I would look at a 5ishk truck for now, focus on getting a processor, couple saws, skidder, delimber, log truck, etc.
As far are your question, a 1 ton is "meh" for hauling. It will do it, but it will be right on the line of being too overloaded.
Figure you want to haul at least 2 cords in it. That's about 10,000lbs +- a few thous.
A 450 or 550 will handle it better (not to mention be legal). Though then you need to plate it commericial if you aren't setup as a farm. For here that's about a $600 difference in cost just on the registration.
What are you looking for the PTO winch for? The truck would be used to deliver firewood? I don't get into spots that I would get stuck. If the customer has that kind of goat trail driveway I dump it near the highway and they can figure it out. I don't risk my truck.
