Ian, the gas will still be about 1/2 of what it is here in Switzerland......
WinchDoc, I have seen the sports tubes here on RC Groups, but cant find any here. But this option will also give (I hope) good protection while traveling in the car. We are planing on driving about 5'000 miles.
Checkenbach, Thanks for the tip, not sure if Avis do Toyota's. Not sure if a minavan is the way to go or a SUV, we will just have to take a look when we are there.
Minhuahua, are your going to Sore Utah? I will let you know when we are on our way down SoCal.
Attached are a couple of photos of the box I have started on this afternoon. I hope it will stand up to the baggage "throwers"
