I follow this gentleman and his woes with his Rpod. Having the kitchen in the back puts more stress on the floor whereas my RP190 has only a table and no walking around weight that the models have with a kitchen in the back.

Please take a look at John's videos on his rpod and this efforts to get FR to do something.

He has alot of good information. Subscribe and get more knowledge & power.

Several of 179 owners have followed his advice and installed floor braces similar to what the factory has done.

The fix involves finding someone to fabricate a brace for you. The materials are not too expensive. The expensive part is geting it cut and welded to the right dimensions. with plates drilled so the brace can be installed. It has to be the width between the frame which may vary by a little, so measure carefully so it will go in and not leave any big gaps between the plate and frame.

If you want it powder coated, that will be extra. Mine came unpainted, so I had to wire brush it and then paint it. Some prices will vary depending on whether you can do the welding yourself or whether you need to find a metal shop to do the work. Total should still come to under $100. You can use the same type #14 self-drilling/tapping screws used by FR in the rest of the braces to install it.
