So far, the longest distance from home in our Travco has been about 175 miles away. I have gone through it and made it reliable down to the new tires I recently installed. (and the many spare parts that I carry)
I read your reply to my wife and we both agree... we aren't getting any younger. I am 45 but I don't want to wait 15 or more years to do this. We have taken long distance motorcycle trips for years and now we plan to start taking a few of those trips in our Travco. Basically, we are waiting for our kids get older and move out. I may have to sign one of them up for the military or something.
Right now the plan is to full time in our Travco 270 for the first year and then move to a 5th wheel toy hauler so we can carry our Harleys with us on the road. I know how things can change but its the plan for now.
