I have been looking at the Valterra EZ hose carriers and fittings. The brackets and ends are available from Amazon. It looks like the tubes are made out of 4" PVC drain field line. not Sch. 40, which makes them fairly light
and inexpensive compared to Sch-40 PVC. I have to see what fittings are available for the thin PVC. I have used 5" PVC fence posts for hose carriers before but they are also fairly expensive.
