If water and mud are a problem for you on a regular basis go back to vinyl floors. That was what it did in my pickup because I knew I could not keep the carpet from getting soaked or mudded up. They are also available from the carpet places. With a backing as well.
I used roll-on bedliner on a jeep cherokee I used to own, it worked pretty well.
I painted my interior with cool seal. It's a thick, white rubber roof coating. Brush-on.
Not where you can see it but on the firewall,.. and the roof,.. might have done the floor.
I don't have a head liner and the roof support brackets weren't stuck to the roof anymore.
Reshaping the roof supports and sticking them with panel bond adhesive made it a little more quiet,.. but 2 coats of cool seal really took the tin can sound out riding down the road or shutting the door.
I second the blue, closed cell foam, camping matts for under the carpet.
I'm going to stick those to the roof too, before I put a headliner on.
Try aircraft spruce. They have a few different kinds of sound proofing material and some are pretty cheap. All different thickness's as well.
ear plugs are the cheapest and easyest.... the next but more costly is a huge sub and a kick a$$ sterieo lmao.....
so did you toss your old carpet or do you still have it? if you do still have it...cut out the rot and get a couple of those door mats...not the hugely thick ones....more like the outdoor carpet ones and cut them to cover the holes in the cars carpet... will work till the warmer weather get here and easy to clean and dry out to...
I decided I'm doing my carpets on Jezzie, and since I'm going to have the carpet out it makes sense to try and do some sound deadening as well. I settled on this stuff:

http://www.roadblockr.com/products.phpI ordered 4 sheets of it (they're 2x4 each). Hopefully that'll do! I read elsewhere of people having trouble getting their carpets in when using thicker stuff, and I know this stuff is pretty effective. It's basically the same stuff as Dynamat. I remember with my truck that even a very small patch can make a substantial difference in terms of removing vibration / reflections from a panel so we'll see what we get. I want to cover as much of the floor in the front as possible up the firewall.
Just remember when you install it to wear the proper white shirt and black jacket. I wonder if this is a black tie affair?
