Single person - How difficult to do everything by yourself?

Again, I want to thank everyone for their replies. I am really leaning toward a MH/toad combination. I think that combination would fit me the best. My current vehicle is towable on a dolly, so I may consider getting one that I can tow 4 down. I have a Jeep Renegade (now my 5th jeep) which would have been ideal if it was capable of towing 4 down. I love the gas mileage it gets. But I still have time to get a different vehicle if I decide.
