Floor Flex or popping?

[thekennys]

on my 3400RL in the rear 1/4 of the rig when I walk on it there is a bounce of the floor.
I think it may not be attached to the frame in the rear anymore
so has anybody had the experience of reattaching it to the frame?

You'd have to drop part of the belly pan and measure where the floor trusses are. They are few and far between and not on 24" centers like a stick house. Mine are not even spaced equally. They're not much of a truss either. Or ... someone may have an easier approach.

are the floor boards screwed from the top or up from the bottom?

We had the same problem in front of our Television in our 2007 3400. The carpet had to be pulled back and the floor reattached. The boards were screwed from the top.

exact info
I assume with carpet back old screw holes show stud lines

...unless the original assembler at the factory missed the truss to begin with! Potentially, that scenario is not outside the realm of possibilities.

The reason I eluded to measuring where the floor beams are is there is a small device out that has 3 feet that holds pressure on the wood part of the floor right over the carpet while you install a screw down thru a guide in the middle of it. It kinda sorta works and would eliminate pulling up the carpet and then trying to get it back under the slide ramps and all pulled tight again. I've seen a carpenter use one of these, but don't know who sells them.

unless things are different from rig to rig...i think what you will find if you look up from the bottom is that the plywood or the chipboard flooring used is attached with really thick bodied vertially ribbed nails that are driven through the "wood" (term used loosely if you have chipboard) and into one inch square metal tube. Not even like stick built homes. I can see several cases where these nails missed the tubing when i look in the pass through storage area at my bedroom floor. Anyone on the moc have a picture of a lippert frame prior to anything on it so people can see what i am talking about? John

thanks
the through caret fixtures I have seen this old house use to stop squeaking floors
I hadn't thought of the carpet end under slide outs
all things being equal i'll look at slide out end and if feasible roll back carpet from rear toedge of iseland and screw in to joices and then learn how to stretch carpet
I saw a YouTube where someone blocked up slide outs to give space to work
