"Thor put a useless sewer hose storage pipe on the 29H next to the bin with the transfer switch and shore power cable. The opening is too small for a sewer hose with the connections so I already installed a Valterra hose carrier under the rig so I can keep the hose out of the storage bin. "
Where'd you put the carrier? I added mine at the rear of the rig, and used the hitch framework as my anchor for it.
That useless tube might come in handy for storing fishing poles...
