We are currently in FL, moving to TX in a few weeks. We also hope to make a trip to the Fort next year, from TX, with our pop-up. My question is in regard to traveling I-10 in AL and the tunnel through Mobile. I would assume that the propane tank is considered a Hazmat for tunnel purposes? If so, for those of you who travel this route to and from Ft. Wilderness, what route do you take? Thanks in advance for your help! This is a great forum and I look forward to getting more involved in it when we start doing more camping! .
