I have a question about running propane pipe into the galley. I currently have the same 1/2 inch pipe (as the pic below I took from the how's it hanging thread) running under the camper, from front to back, through holes in the frame. We were planning on using some flex pipe to go from the end of the iron pipe through the floor and up to the stove. However, we were told recently that "they" don't like flex pipe on the outside and that we need to run hard pipe up through the floor. I noticed the picture below and thought I would ask if that is the best way to do it, or if anyone knows if the DOT would have a conniption if we did it the way we were initially thinking.

I perused this subforum for a while and haven't come across the answer to my question so I thought I would start a new thread for a question that has probably been answered a hundred times in the past. Thanks for your help!
