Is extra gas needed

Fanrgs, You traveled a lot of diff. roads. I don't think we will be traveling that many. We plan on staying on the major roads with the TT. Maybe park the TT and take the truck on others. Question, on which roads did you have the most flats? I am now rethinking and might take two gas cans. I do have all the tools for fixing a flat. I have one spare for each which are on rims and in good shape. I have no room for anymore. It is a short box. I think a slow drive is in order.
AKsilvereagle, Thanks for the information. I think two cans. All of this information is being put in a folder. I can't thank all of you enough. R&M
