mystery crack

[denism29]

This crack is from the bottom corner of the bed pullout and mysteriously closes when on the jacks and opens when on the truck. The meticulous observation shows that contrary to the first observation, thisx not caused by a torsion movement but by a completely vertical movement of nearly 1/8 of an inch. After removing the bottom section I found nothing cracked on the frame, all the welds seem to be OK. While parked on the jacks, we repaired with two coats of fiberglass matt with resin and on the first few miles on the truck it cracked again.. Any suggestion anybody ?????????????

On the top the crack is closed ; on jacks
On the bottom the crack is open ; on the truck The grey is the primer , the top coat has been pulled by the temporary tape put on for traveling.

Sounds like a job for the pro's. If it is flex from the frame it could be a major problem. Is it a Lippert frame? Check around for a rv dealer that deals with problems like this.

I have seen the same cracks on my friends 2004 Jayco5th wheel below bedroom slide. The RV repair place said it was the wall flexing from the roller guide misaligned.

I know the pullouts and the axles are from Lippert but how do you find the frame manufacturer??????????????? The frame is twisted a bit, when the front is level, the rear slopes to the right ; is it a trademark of Lippert ?????????????????

Maybe it's prevalent in all Crossroad products as more than a few Redwood owners are reporting stress cracks as shown in the first pic... the second picture shows what MOST manufacturers do to give that stress area some flexibility so it doesn't crack because that area WILL move some...

At least I'm not the only one !!!!! Do you know what is the cause of the problem or what is the solution to keep the water from getting in ? Or what is done to repair it ? AAAAAHHH the pleasures of camping, Imean of repairing.

YESSSSSS....now I know why t here was a plastic strip with silicone on the beginning of the crack. I though the first owner had hidden the crack with a pladtic strip. So I will repair the crack an make one vertical and hide it Under a plastic strip .....after removing thebottom from the back and not from the front cause it is screwed Under the fiberglass cap which I dont want to dismantle. Then I will have to glue styrofoam Under the bedroom floor and remove the water soaked fiberglass isolation. Hours of pleasure coming up to enjoy.. Thank you for the info.

My 2007 cf30sk cracked at the same location but not anywhere near as bad. Mine was a hairline straight down. It was corrected with a plastic spacer and caulk (after the sidewall was "grooved out") and has not returned. It agree it is the wall flexing at that small weak spot.
