anchoring a subfloor in a van

So I pulled up the nasty carpet in my 93 Chevy van. I’m contemplating on what to put down in its place. I plan to start with a plywood subfloor.

Some noise suppression seems ideal. Also, do you anchor the subfloor with sheet metal screws and just hope that you don’t hit something important?

Any suggestions would be appreciated

Thanks

In the past we've always used sheet metal screws. You MUST crawl around under the van and take note what is in the way and what you don't want to sink a screw into. Some folks in the past have just sunk screws and "vented" their gas tanks or something else that isn't supposed to have a screw in it (a hot wire that suddenly has a ground via a screw and metal floor is very bad news). Some use a insulator on the floor before putting the subfloor in, some don't, if you are carpeting the floor that will provide pretty good sound deadener. Don't use thin plywood for the subfloor, get some thicker stuff. Remember, you don't have to use a ton of screws to put your floor in, just enough to keep it from bouncing up and slamming down on bumps. In addition to sheet metal screws, you can get away with exterior grade deck screws, most will screw in without drilling a hole first.

Thanks Starlord

I don't think I am going back down with carpet. What are people using for sound dampening? It there something that I can put in between the subfloor and the top flooring? The top flooring will be some fake wood floor that you might put down in the kitchen


Thanks

I was considering using "T" bolts through the plywood and using nuts under the floor. Would that not be much more solid of a plan than self-tappers? More serviceable in the future too?

I used the cabinets (which are anchored to the wall struts) , the bed (also anchored to the wall) and the front console to hold down the sub-floor. I'm not much for drilling holes anywhere in the exterior body work if I can figure a way to avoid it.... smile
I used those anti-fatigue mats cut into strips and laid in the low tracks of the van floor to give a level surface. Thin (cross-hatch) sub-floor, reflectex and then plywood. Finished with carpet with a strong backing (actually a rug cut to fit) so it would lay flat. We camp in ours a lot so we needed something that was "bare-foot" friendly.
Our storage area under the bed is a finished panel material to make it easy to vacuum and keep clean.
I got pics somewhere.......



Hi, I don't care, thanks.
