This outfit is heading across the country after having started at Sarasota, FL about a month ago. Old John Deere A with a truck cab mounted on it. From pictures it looks like the alternator or generator has been up sized to handle the lights from the camp trailer behind it. And there is something like a tom-tom navigation display in the cab with GPS route headings for the driver. There are twin straight pipes coming out the hood if you look closely. There maybe other mods made to the tractor not obvious to me, but you have to be pretty brave to head across country on an old rig like this. There appears to be no support vehicles following him, so he does his own flat tire changes on the camper and minor mechanical work when he can handle it. He is making maybe 50 miles a day and was in Vernon, TX yesterday. He collects money for a fund drive for US veterans just about wherever he stops. Got to give the guy a big E for effort and a bunch of credit for what he is doing.
