I can't send pictures right now, because I'm away from home but I made two storage tubes out of 5" PVC fence posts and mounted them forward of the tanks on our 25' Safari. I used plain pyramid caps and mounted the ones on road side with hinges and latches and the ones on curbside with screws. The trailer originally had two of the round tubes but they were too short and not big enough diameter for the new sewer hoses I bought. Of the two tubes, the aft one holds the sewer hose and extension and the forward one hold three flagpoles.
