Back bed is sagging

[Livin4wkends]

This is our new Cub. The back double bed looks like it is sagging a little both inside and outside. We can't figure it out. We tried switching the poles from the front to the back but that won't work because they are different sizes. The cord inside that keeps it from flipping all the way down while setting up isn't even tight, it has some slack. My dh said that there may be a bent support piece and is going to try to bend it back a little. Any suggestions or experience with this??
Thanks for your responses!!

I would try and find another support so it will support both ends of bed platform.
The tire may make that difficult but you my be able to make a extension off bumper to support the brace. Most foldout beds on pop-ups we have had had two brace supports. Have even added a 1" board across platform for more firm support.

007 - Thank you for the reply! So you mean attach something to the bumper and insert the pole into that to increase the support? We have the 2 support poles under it and it still does that. We never had anything like that with our popup.

Your front bed looks level does it have two bars for support? You may have room on other side of tire to mount into bumper. The back end canopy looks large with slack in canvas, if you can get bed platfrom level first so no slope in bed, than check to see if you can dress excess canvas inside TT so it will look ok. Builder may have put wrong bed canvas for opening you have.
You should level main body of TT than measure bed platform level for size of support bars you will need to keep it that way. Use 2x4's to support bed to do this.

We have a 05' Aerolite Cub where it was doing the same thing. But we have a different type of bunk support system. We don't have any outside poles. The newer ones are supported by inside cables only. One on each side of the bunk ends. I have noticed a few people with newer Cubs having problems with the bunk material separating at the top of the bunk where it attaches to the trailer wall near the roof line. About a year ago I notice mine had a small 1" area that looked like it was starting to separate. The root cause is there are 3 adjustment holes where the cable attaches inside. The factory would use the lowest hole which in turn allow the bunk to rest about a 1/2" lower. I'm assuming after a few years the material would shrink a hair causing the material to be tighter , thus pulling at the seam on the top of the bunk ends. I moved the cable to the middle hole, which in turn gave the bunk material more room, thus not pull at the seam at the top of the bunk ends as tight.
Take a look at the top of your bunk ends and see if you are seeing any material pulling away from the seam that runs along the top of the bunk ends.

Thank you again for all of the replies. My husband ended up moving the brackets down about an inch on the bed to make the bed level. It looks and feels great now. What my thought is....someone before us either lost or damaged a pole and got 2 replacements that weren't quite the correct size but close enough....hence the slight sag.
Oh well, it all worked out and thanks again for the responses!

Keep an eye on the tenting material on the top of your bunk ends. The extra stress might have caused the material to tear.....

Thanks Jim for the tip. I'll keep an eye on my bunk ends. I did notice the material being tight against the top like you said.. We haven't had a chance to get out more like we wanted this year. Now that I'm healing, we might be able to..

I really didn't notice mine being that tight till another Cub owner with a newer one showed me where to look. To get a good look you need to get on a small ladder to look along the top where the tenting material meets the molding or channel ("J" channel) that attaches the tent material to the trailer.
