Brake smoking ?

Check your state laws about allowing any fluids to drain from your Pod.  Last year after doing a dump at a State Park, I realized that my fresh water tank was half full, so I opened the drain valve.  After a couple of miles, I noticed that the dripping water was creating a vapor trail behind the Pod.  After a brief moment of panic I realized that the vapor was water vapor and continued on my way.  After a few minutes, I had a State Trooper pass me and pull me over. I knew I wasn't speeding, etc.  He walked over to me and said that when he first saw me, he thought my brakes were on fire.  Then he noticed that the fresh water valve was dripping on the pavement.  He informed me that in Minnesota it was illegal to allow any fluids from a RV vehicle to drip on the pavement.  The state was worried that people would try to dump black water onto the highways. He didn't give me a ticket, just a verbal warning.
The worst case I ever saw, was when I was on the Big Island of Hawaii, following a small RV.  He must have just completely filled his gas tank, but didn't put the cap back on.  Every time he went around a tight curve, gas came spilling out.  It was a two lane road with no pull offs and about twenty cars following him.  We had to drive about ten very slow miles behind him, slow getting sick from the fumes.  He never noticed he had lost quite a few gallons of gas.  We finally were able to pull over...took us about an hour to recover.

Thanks for sharing that information with us. I would have panicked, also, seeing that "smoke" coming from the back of my pod. One more thing chalked up to experience.
