OK Lets talk Sewer Mods!

So after today's...conversations...:roll eyes:...I went shopping at Lowe's and here is the scoop from my POV:

Rhinoflex with sewer attachments is just over the 4x4' bumper in a RV (OK this is issue #2 I will be discussing with Forest River CEO @ Goshen...)

So the REAL fix is the &^%$@!! Industry needs to make 5x5' bumpers - how the hell hard is that?!

So the MOD is: a 5x5" PVC fence post in Lowe's - 96" long so I will have to cut it down to fit the bumper BUT....

It will hold 3 Rhinoflex tubes - 1 5ft & 2 15ft collapsed with connecters on them. I have glued the 45 deg adapters on the sewer so they are done.

This will hold the sewer and I believe eliminate a sewer box from the basement!

As I see it this will store everything I need - hoses and connectors! All I need is the camp sewer connector (and I can put that in the RV chemicals box)

Issues before I start the mod:

How can I secure the end caps (BIG PROBLEM!) The post has end caps you can buy but they are not press-to fit...they "sit" on top (you are supposed to glue them in place)

The post is 5x5" - if I secure it to the bumper (4x4") what would you use?

OR....should I see about securing it close to the Grey/Black valves?

I've had the rhino-flex since I got this TT. It fits in the bumper fine, with the 90* elbow on the discharge, if you line up the "tabs" on the coupler with the corners of the bumper.

Only problem I've had is it slipping too far into the bumper and not being able to get hold of it to pull it out. Solved that issue by making a handle with a long wire-tie (zip tie).

I feel your pain. I just got a new 5th wheel and a Rhino hose to go with it. Its jammed tight in bumper right now, but don't like it. I'm thinking some 6 inch PVC mounted under the TT in front of the axle near the drain outlet. No problems with choices of hardware or end caps for PVC

This is what I did. Put cap on, drilled a whole straight thru, bought some, I believe 8" 5/16 bolts cut off threads, and tapered the end. Drilled a. 1/8 inch hole in it thru the bottom and thru the head ( i was going to add a cable between the clip and the bolt head, havent gotten to it yet) and use a hair pin clip to hold it.

Dave,

I was thinking that as well but the 6" PVC is *thick* and (compared to the fencepost) weighs a ton!

I am not usually a weight nazi, but I am putting enough mods on my 5er now to where I am considering weight when I can

Landscape nails might work too, I used a 5" cap on a 4 3/4" post cover, so that way I didnt have to worry about venting the end.

I like the idea, as far as mounting I would leave it on the bumper, less accidental fumes below the trailer, and the bumper will support any weight. I would think of some carriage bolts with some big ol' fender washers and fasten that to your bumper. That will allow for any stress on the plastic to be distributed. (not that there should be much) As far as the end caps, i would use a long stainless bolt (rust resistant) and a wing nut. Drill through both sides of the end cap and post.

Put 2 push button pins on each end of both fence post covers.

the whole trailers are assembled randomly

mine is in there, but it takes some work to make it happen. Never had a problem with the cheaper hoses.

My rhino fits in my Roo bumper just fine as others have posted. You just have to twist end so tabs fit. Love my Rhino!

your right about that. I haven't gone browsing for a fix yet, but its on my "to do" list. PVC sewer drain pipe is MUCH thinner and lighter than supply PVC pipe. Still plenty of fittings to choose from. Maybe our bumpers aren't truly 4" and it will fit in 4" pipe. Need to do some figuring.

obviously not all bumpers are created the same. I will get a measurement on the bumper and see if it falls short of 4". Mine is so tight I'm afraid I will damage it.

Two small hinges pop riveted into place and a toggle latch to hold it shut with a pin through to keep it "locked".

4" PVC didn't work for me. I had some already and just looking at it I thought that it would work.... 1/16th to a 1/8th inch too small... Fold up step ladder will not fit either...

This is how I did mine used rivets to close one end and put hinges and latches on the other to swing open so far they work great being next to the drain makes it easy to load also. I put them on at a 1" drop on closed end and drilled several holes for drainage.

The 5' folding ladder is all I put in our 4" bumper along with a laundry drying board.
