The vinyl planking products I've used are all thicker and harder than sheet goods.

Ply gem seems to have a better reputation, warranty, and thicker frames.

Once it's down if can't be taken apart.Key thing is to get the thicker type for more durability.Don't know how well noise travels with either.

Since the walls are thicker, you lose a little interior footage compared relatively to what stick homes look like on the outside.

I replaced the floor with thicker materials (hardiebacker between tile and underneath sub floors. there are two layers of plywood so I used screw to fasten them again).

Always assume that tenants will be very hard on the floor and generally the thicker the wear layer, the more durable to wear and tear the floor is

If the basement is very large you might go thicker, cut in stress fracture points, or lay in some mesh to avoid it cracking badly.

The plaster was a lot thicker than the drywall will be. 

I built a house and used upgraded subfloors, thicker walls for greater insulation, etc. and lost my *** on the build.

I have seen some they have gone over with hardboard or even thicker plywood over the old subfloor, but I don't like that option because it always seems to leave uneven places and decreases your headroom which is tight in older MHs even further.
