What type of Floor Coverings do you use on the floor of your Transporters

Just about finished building a 40 foot transporter, and wondering what do most guys use on the floor of their transporter, we have a wooden floor, but want to cover this, in where the Funny Car will sit, and the accomodiation area up front.
Our throughts are too carpet it with underfelt under the carpet in the accomodiation area. and can also get a style of carpet that you can lay on your garage floor to put in the storage area where the car will sit.

 

Most high end trailer manufactures use coin pattern vinyl flooring

 

Armorthane , Spray in bedliner material. Slip resistant, colored as you wish, tough as hell and water tight. Pressure wash it out with out trapping any water etc. Oil and gas resistant. Ok, Ya I apply it!! I do a bunch of trailers and everyone loves it. It is kinda spendy though.
