One problem with putting wood down , wood can get wet , then start to rot.Unless you use treated wood , and then that can start to get expensive.If I find my carpet in the front get ratty , I think my first option would be to go with what I did in the van , that foam insualtion , then some bed liner spray , and then some of that all weather carpet that can take water and stuff , easy to clean too.That would solve the problem of noise , heat , and also no worries about it getting wet and nasty.If your not in an area like me where we get lots and lots of rain , or you don't go anywhere wet , then , wood could be a viable option.Just speaking from experience as my last van had wood on the floor(work van) , and it rotted , and it got nasty underneath from not being able to vent the water very well.I sold that van before it could get condemmed <img src="/forums/images/graemlins/smile.gif" alt="" /> I won't make that mistake again.
