No heat in bedroom, again.

Good morning everyone,

We have had our new RW for just over a month. We live full time in a cold climate using the fireplace, furnace and a small basement heater.
After the first week of living we noticed there was no heat coming from the master bedroom register. Living room registers were and are working fine. I removed the basement wall and noticed the flexible heating hose and connector had fallen off. all that secures them to the heater vent is very sticky foil ducting tape.
I was able to squeeze my economy size frame up in the area and re-secured the tubing and mount back onto the duct using the same type of foil tape the manufacture used. Tested, all was working well, had great heat flow thru all of the registers. Buttoned up basement walls and thought problem was solved.
Sunday evening we got back to the trailer and my wife noticed that the bedroom was not a warm as the rest of the trailer. So the first place I went was the heat register in the bedroom. Again, NO HEAT!
I went out to the basement and shined my lite thru the water filter access door and wouldn't you know it, there was the same hoses laying on the floor. It came of again exactly like before but I even added extra foil tape to secure them up there.
Now for the question. Is there a better tape to secure theses hose up to the heater duct? Or has anyone had this problem and designed something better?
Its not hard to access the area, its just a pain to try and fix in the middle of winter. I would have thought that the factory would have been smarter than this thinking tape would keep all this up on the ceiling.
There is always a better way, I think.

Any comments, help or suggestions?

Can you squeeze in there again and try using a round duct clamp similar to the one used on a dryer vent hose(s) ? Also saw a commercial for a product called "Gorilla Tape" which is suppost to have super holding power. Any way to snap a pic. so we can see ? Darn shame to spend big $$$ on a new 5er and have something as frustrating as this occur because of sloppy quality control. I just saw a video of another manufacturer producing their 5th wheels and it looked like the technicians were scurrying around at record speed to keep up with the production line. How can you put out a quality unit without taking your time & doing things properly ? My new 39MB is on order & I'm just keeping my fingers crossed.

I had the same problems and think my bedroom one has fallen off again. It is a cheap way to do it. I have a spool of gorilla tape going to try in a week or two. I used some screws but they apparently didn't hold.

even the home heating systems use the foil tape, but maybe the surfaces are cleaned better and don't move as much as our moving earthquakes

I believe that Dave said they were "rolling earthquakes". Dave can you resolve this controversy?

There should be a mechanical fastener to secure heat duct hose to the duct work. Either a few screws and then foil tape it or a large dryer vent sized hose clamp and then foil tape it. Code I believe. Most metal pieces come from the factories with a slight amount of oil on them. If not cleaned before taping I am sure they will keep falling down.

There is a tape out there specific for flexible duct (Home Depot). Foil tape is not the best for flexible.

A mechanical fastener must be used. ANSI 119.2 Which is RVIA code. Page H-92 5.7.3
Secure it then tape it!!!

I secured the duct to the bottom flare of the register with a screw, taped it with duct tape and then took some of the zip ties with an end for a mounting screw and supported the duct so it couldn't fall down.
That was 2 years ago and so far so good. I'm going to be in the basement in a few weeks chasing a water pressure issue and am planning on adding some storage and re-doing the back walls. Going to do some "straightening up" while I'm in there. Wiring and plumbing look like a rats nest and bugs me.

Thanks guys for all of the suggestions. The hose itself is staying secure to the piece that actually mounts to the duct. Its the mount piece that wont stay up.
I'm going to try the gorilla tape and some mechanical fasteners plus secure the hoses so there isn't as much downward force pulling from the hoses.

I'm with you PG , that basement plumbing and electrical is a rats nest and needs to be cleaned up for sure. A little wood frame or something to secure the heating mount would be a very nice thing to avoid this issue from happening to others.
