x2 on where in VT are you? If you guys get some type of trailer I would be willing to tow it to most places in the new england area for you with my old ford f-250 (not very fast going, but she'll pull anything anywhere). Maybe we can get it a place near ArmyRover and if needed I can give a hand doing some of the work. Cost of tow would be lunch thats it. One condition is I can't do anything for the next two weeks when my shoulder will be all healed up.
