Would you pay a welder to reinforce your 5th?

I'm considering paying a RV industry welder to add gussets /reinforce the welds in the under deck / pin box area.

A warranty repair for a crack under the bedroom slide was just completed. As part of repair, the under deck flex was measured @ 1/2" on both sides which is, according to Forest River, within spec. I'm leaning towards leaving it but while its at the dealer and apart, I'm considering having it reinforced to possibly to mitigate future issues.

According to Forest River (below) it won't violate my warranty which has expired anyway. Its a 2018, 13 month old 5th wheel.

FR ADVISED THAT THE FLEX AMOUNTS ARE NORMAL, THE CX MAY ADD GUSSETS FOR SUPPORT AT THEIR OWN EXPENSE BUT ANY AFTERMARKET REPAIRS ARE NOT COVERED UNDER WARRANTY. ADDING GUSSETS DOES NOT VOID WARRANTY AS LONG AS THE ORIGINAL FRAMING IS UNAFFECTED/CUT. AC

I'm supposed to review the scope of work and cost with the welder next week. I value the opinions here in RV,net; would you do it?

Thank you,

  • If lippert built the frame, it's bound to crack. Lippert hires their 'welders'from fast food resturants. If I owned your RV, I'd do the work myself but then I can weld and own the equipment too.

    Great point and Yes, I was thinking about that too. Reinforcing the structure may make it too brittle and that could cause other issues. RV frames need some flex so it can bend under stress and not break.

    A good friend of mine works at the Forest River dealer that did the inspection / repair to the crack under bedroom slide. This isn't the dealer that I bought the 5th from which is 1400 miles away.

    The dealer offered to give me the contact information to their contract mobile RV welder so it doesn't have to go through the dealership because they would up charge the welder's price.

    The dealer looked over the welds when the under deck cover was off, they said they were OK. The side wall welds were horrible where the crack under the bedroom slide occurred. All of them were small tack welds and one of them broke. The broken weld wasn't where the crack under the bedroom slide occured, so I requested Forest River to remove the under deck cover and inspect welds in the frame. It took 6 week for them to approve it and perform the work.
  • My thought would be where and how are they measuring the flex? If you measure it at the right place, a huge amount of flex will be within spec.

  • Add as indicated while its open. If you plan to keep it for a while.
