BLACK TANK TUBE HANGER

Nice work! We had that happen to our 179. We did a similar repair but used 28 gauge galvanized metal perforated plumbers tape. it held for the last 2+ years that we had the 179.

I have a 2019 rpod190 and on our maiden voyage the black tank strap broke. The pipe can hold 5 gals of waste easily and that's over 40 lbs. The strap holding the tank is the leftover from the metal stud to the frame. The manufacturer carried it down to hold the tank tube. The bouncing over 1000 miles caused it to fail and the gate value broke off from dragging on the ground and damaged the grey tank gate valve when we were in the middle of nowhere. I called the 800# and it was a waste of time. Found a coat hanger to tie it up for the trip, but could not use the toilet or grey tanks. I added my own strap as you have done and NEVER travel without a small roll of #18 fence wire for emergency repairs. If you can avoid using he toilet while traveling, that water wont build up in the 4 ft 3" pipe and put force on the factory strap. Definitely add your own!!!

Not only forest river has this issue. Winnebago has it for sure. I think they all use the same crappy parts 

Thanks for the info on 6061 aluminum - there is a welding shop around here I can probably get to start with a 12" x 1-1/2" x 1/8" stainless steel strap and make the bends for me.  I can cut it to length as needed and drill the two holes that would  be needed to match the two already in the frame.

I would be cautious about using 6061 alum to make a hanger. Although it's pliable. it doesn't like to be bent anywhere near 90 degrees. 5052 is aluminum meant for bending to extreme angles, commonly called sheet metal. Many use muffler clamps, and they seem to work well. I made mine from parts available at the hardware store.
