Reb, I hope you don't mind my butting into an old thread, but I was cureous about an earlier post you wrote, stating that one of the M967's would be used to carry water. Someone in town here wants to sell me a nice M969, but I am equivocating because I haven't yet had time to discover whether you could carry and pump (?different pump mechanics) water on the highway if the trailer is made for fuel. I contract with BLM to carry 1200 gal water off road or 2400 gal if deliverable on a gravel/dirt road to support fire crews. If my wife could get her CDL she could follow, pulling the M969 with our M915 and I would have a "mothership" capable of 3-4 refills, and this way I can have quicker turnaround rather than sucking from a dry mudhole. Most water tenders are single tanks incorporated into a single vehicle; not a semi. So she would have to stand back 20 miles or so, and I would fetch the water from her supply. Since water is denser than diesel and aircraft fuels I realize I would not be able to haul a full tanker filled with water. I was just wondering if you had any thoughts re the compatibility of a single hull of 304SS hauling water on public roads; would folks frown on it? Would the pumps work as well, given different densities? The BLM will be the final arbitor, but I haven't spoken with them yet. Don't know if they allow semi's on a gravel road pointing toard a fire. My tactical truck is the M923 with nicely fabricated Al tank. Thanks. Gary.
