Purchased a new, longer sewer hose a few months back but it's just a tad to big (OD of connectors) to slid into 4" square tube bumper without possibly getting stuck......, so had to come up with something else.
Went with a (1) 5" x 5" x 8ft.lg. PVC fence post, (2) 4" wide square bend U-bolts (bent to fit), steel strap, and some fastners....., along with a little gloss black paint over the white PVC finished it off:
The Eagle sits pretty high so I have plenty of ground clearance, and I drilled a few clearance holes along the bottom of the PVC tube for drainage and venting. Do to the spare tire mounting hardware on the bumper I had to install two spacer blocks (have to paint them yet) between the bumper and PVC tube.
I was considering mounting near the TT sewer dump valve connection, but do to the low hung LP gas piping
and a few other issues, plus drilling thru the I-beam frame for mounting...., I went via the path of least resistance
