1999 MH wallboard replacement

Just bought a 1999 MH and it has standard wallboard's. I was wondering if replacing all the walls and floors with drywall would add to much weight to the home and cause it to sink or cause cracks or other damage. We dont plan on ever moving it, but we do plan on putting a permanent foundation under it.

Welcome to the forums Seth!
I have an untitled MH from somewhere around 1970 that I've built a house around. I have 1/2" drywall on most of the walls and ceilings. I did beef up the ceiling framing. I also added plywood on the floors. Most of the work was done 20+ yrs ago and I have no settlement issues.

Cannot say if it will sink.
Depends on what is supporting it now.
Also what type of soil it is on etc. etc.
Too many variables.

Why not wait till you get a proper foundation under it?

Normally a MH is supported under the frame with the front/back cantilevered out. If you are just underpinning the perimeter with block there isn't a lot of support from that foundation wall. How long has the MH been at it's current location? Some locales require concrete under the piers but most of the older ones just had cat blocks under the piers. The longer it's been since the MH was set up the less risk their is of settlement.

Well the floor has a few water spots so we are going to replace the floor throughout with plywood and figured we might as well replace the wallboards while we are doing the floors. And not sure on how long MH has been at current location, will get back to you on that when i can. Also i have a couple of photos from underneath the MH would that help at all to determine anything?

MHs are pretty much all framed up the same. They use 2x6s for floor joists with most using particle board for the subfloor. I often cut out just the bad PB and replace with 5/8" plywood or OSB and then laminate over the entire floor with 3/8" or 1/2" plywood. Normally the floor damage is limited to the perimeter and where the plumbing is.
