To Mod or not to Mod, there was no question.
After only being used 4-5 times at the dump station my Warrior provided paper-thin 10' sewer hose had developed 6-8 pin holes in it.
Last fall I went to Camping World and bought a Super Heavy Duty 10'er. When I put the new hose in the manufacturer provided storage compartment, it liked about 3" fitting in far enough to close the door so I was forced to Mod.
I went to Lowes and bought the thinnest walled 4" PVC pipe they had. Using my drimmel tool, I cut all but the first 3" of the original black storage tube off the door assembly. I took some measurements then cut the new PVC to 74". Again using the drimmel tool I beveled the outer edge of the black tube and the inner edge of the PVC and crammed the PVC onto the black tube. It was a real tight fit. As you can see from the pictures below, the new tube fit nicely between the front of the RV and the vertical bed support. This is basically unusable space anyway.
I capped the other end and strapped it to the vertical support. I did not glue the cap so I could access the 20' sewer hose from that end.
With over 74" of tube, I am sure I can store a 20' hose behind the 10'er and have it available if I ever need a longer hose.
