underbelly

I've got a 2018 Mallard and need to get the cover off the underbelly, but the heads keep sheering off the screws. I've tried by hand, with an impact drill, and normal drill. None of them unscrew. Instead, the top of the screw just twists until it has twisted off. They are weird looking for...

Decided I wanted to drop the belly coroplast to check for build issues, maybe add some tank bracing / insulation, etc. What I discovered is that my coroplast is attached to the outer frame rails with pins, not screws. My first clue was the black plastic centering collar, used to center a...

Opened the partition in the storage area of my 3270RS Bighorn today for the first time. Wanted to scope things out down there. I located the converter in there, obviously the furnace and all the electric and water lines. I then vacuumed up metal and wood shavings. I then noticed the two duct...

Hi everyone, I'm hoping someone wiser than I can point me in the right direction here. A while back I had dumped my black tank and was filling it back up to flush it by putting a chock in the toilet which keeps it open to fill. Anyway, my neighbor distracted me with some fish tales (LOL) and...

Heck of a 24 hrs. RV (2015 Heartland Gateway 3650bh) delivered about 3PM Friday. RV dealer or salesman didn't tell us they'd winterized unit, which entails of opening all faucets and plugging all drains. Smelled smoke, smoke alarm went off, after searching inside seeing nothing, ran outside...

I have recently discovered the underbelly liner was sagging. I poked it with a knife and water ran out for several hours. Apparently I have a leak somewhere. I removed the access panels to behind the UDC, under the shower and bath sink, and around the water heater. I could find no evidence...

I had a leak in the underbelly and covering was cut to gain access by the dealer. What is the best way to piece it back together. The dealer used tape which of course didn't stick very long. Of course I didn't notice that until the tape started to fall down. My bad for not checking.

Hi everyone, I would like to thank everyone in advance for your opinions and suggestions. Taking you back in time about a month and half ago a blackwater leak was found and the coroplast belly material held quite a few gallons of smelly stuff. It was repaired (cross threaded connection and...

I own a 2010 Big Country 3550TSL. Recently my entire rear #2 Gray tank unloaded into my underbelly. After the foul stench had subsided, my repair men showed me how the tank was mounted. The incredible sag in the tank caused it to pull away from the connection to it's drain line. Now sagging...

Well guys, I got a new one for you.... The last time I posted was new years. We were on our last trip to Williams and our unit froze. We had three water leaks and a blown water pump.... I had everything fixed last week for our trip to warm country. We were about 100 miles into our first leg...

I'm curious how the ub is heated? Here in NW Fla we have had record cold temps and I don't know if I had the heater on correctly. The tank monitor panel has a switch for a heater and I assumed it was for the entire ub. Is this correct? Or is it just for the tanks? I could not find info in my...

This afternoon I started getting my 2007 Big Horn 3055RL ready for a trip next week. Yes, here on the central coast of California we can camp year around, but it was a brisk 73 degrees or so. I noticed a large bubble-like protrusion in the material that encloses the underbelly. This huge sag...

any ideals on how to insulate my garage area underbelly want to do it my else. rick

can you give me info on getting the corugated plastic underbelly for my 2010 26srl. i would like to add this to my tt. or link me to the supplier wher i might be able to purchase.

we have a 2010 26srl. did not realize until after buying that we can get the underbelly enclosed as an option. does anyone know a way to do this aftermarket or what type of materiel is used to cover the bottom?

refer to my other post re "trip problems" The fix to the slide awning was simple. New end cap and bracket. Service manager says looks like something clipped and bent the anti furling device which then jammed the bracket when I opened the slide. However, I have a question regarding...

We have just recently placed an order for a Cyclone 3950. I realize that these come with a heated underbelly, but is the option available to have the underbelly insulated at the factory? Risk of freezing seems to be a common problem with those of us stuck in the "Far North". Has anyone had this...

Hello All, We have a 08 2998RB and there is water coming out of the underbelly. I have it at the dealer now and they say that a coupler for the black tank vent is the source of the leak. I don't understand because the water looked and smelled fresh. Can anybody help? I would like to do this...

will plumbing freeze? Okay everyone here ya go: How safe will I be without winterizing my bighorn 3670 with the temps getting into the mid-20's:eek:. I am in Michigan and will be leaving for Texas (yeh-haw!!!!!) on the 20th of this month (just a few more days) and I dont want to winterize. I...

Does anyone know the answer to this question? We bought this unit May 2008 this is a 2009 unit.....and at the time we were told it was a heated underbelly ( by the dealer sales dept) the website for Sundance also appeared to be saying it was, I called our dealer's service dept and he could not...

Hi all we have owned this camper since May of 09 up until recently we thought the underbelly was heated along with being enclosed (that's what the dealer/sales told us) but after reading a few things on this sight I'm worried it may not be, I called the dealer's service dept and they said they...

Does anyone know the thickness of the coroplast underbelly? They gauge it in mm - 2,3,4,5,6,etc - and I want to get the same thickness as the existing. I need to get some more to finish covering the belly of my Cyclone - back where the garage is and the current underbelly stops. I...

We need to remove our underbelly to see if we have a leak in it. Is this a major undertaking? Anything we should know before doing it? Thanks, Mike

OK - after fixing all the other water leaks - shower, outside shower, sewer flush, kitchen sink - I thought I had all my water problems fixed. I come home yesterday and notice a water puddle under the RV. It had rained earlier in the day, and the rest of the driveway was dry by the time I got...

I live in Idaho and it can get a bit cold. My 3950 is suppossed to have a heated underbelly. I have had some of the black covering off underneath and see no ducting for heating of the underbelly. I have also noticed several holes in the frame etc. and gaps in the black undercover that could...
