Someone suggested raising and let it settle?  Then repair! .?? 

Anyone with experience? Our sag is 1.5” in middle and we havent used it since late 2019 because of covid…. So only two seasons of travel? 

Love the damn thing and … lots of great mods  but lots of workmanship issues discovered too….

DIANE AND CHARLIE….sad in Ontario! 

I for one agree that the floors are marginal, and said as much. The whole structural design of the rpods is borderline IMHO.  I don't think that is due to improper welds, I think that FR's laminated floor sandwich is consciously designed and constructed that way to be as low cost in materials and labor and as light as possible. If it doesn't get wet or or overstressed or heavily used then its Ok, if not then its a problem. We see those problems disproportionately on this forum because most owners are happily enjoying their trailers and not having issues, as least so far.

What is the basis for saying that that the axle doesn't need reinforcement if the frame has been reinforced? There have been multiple instances reported of bent axles without frame damage. A stronger heavier frame in no way reduces the load on the axle, in fact it increases it. Which one fails first is going to depend on where the loads are. If they're near the axle then the frame isn't going to be overstressed and the axle will bend first, if they're out at the rear of the trailer than the frame will likely bend first. 

Please correct me if I'm wrong, but I thought Lippert added another frame tube under your existing damaged one, not outriggers to support the floor panel itself? Why would Lippert be responsible for fixing FR's floor problems? 

Thanks for the info.  Will implement at some point.How long does it take to make the modifications?

There are several issues outstanding and most serious can be solved by adding out-riggers to the outside wall. The second is the mod to strengthen the frame at the point of axle mount. With both those done, I don't believe the mod to the axle is required. That's for all you to work out.

Lippert did the out-rigger add for me. They knew the issue and didn't even cough at doing it..

Safe travels my friends!  

That's interesting. Are you saying that FR acknowledged there was a problem with their construction and that outriggers were their recommended fix and something they have made available to dealers? 

Fortunately things have stabilized and I've not had to do that. 

Okay. I took another look at the video. I was thinking of using 1-1/2" angle iron for this, but it looks like that would not provide enough contact surface for the screws. I will need to see if I can find some plates to use for this purpose. It may have to wait until I can make a trip to a metal shop.

As for tack welds, these would not be long enough to allow for 24-27" spacing. The height would only be the same as that of the frame. That is why I was thinking of bolting it. My welding skills are not that good that I would trust trying to weld that close to the floor. However, I will take the advice and use TEK screws instead of bolting the plates if I do this.

We have a 2016 RP179 which was built in 2015. I just looked at ours and there is a little bit of sag at the slide-out, but nothing like 2" I will be looking into adding support there myself. Thanks for the heads-up. If anyone reading this has added outrigger support to the floor, please let us know how this was done.

By the way, we are registered for the FROG rally in August if it is not cancelled. While there, I will try to ask someone from the factory about this and get information on what can be done to fix this issue. Since it is well beyond warranty, I don't expect this to be fixed there, but if I can get information, it will be helpful. It would be nice if the factory would strengthen that part of the floor to take the load of the slide-out better or add an outboard support or two in that area of the frame to better support the floor in that area.
