I'm thinking go the "expensive route" and do Herculiner up the body line on the Tracker or go the "inexpensive route" and get the Duplicolor spray on (in the aerosol (sp?) can) bedliner.
Ugh, you don't want them. Smelly, stained, and fugly.
febreeze?
Ewwwwwww

go half(ass)way and just roll the stuff on yourself.
I was going to do that if I got a 4x4 tracker to kick around.
Herculiner IN and OUT, no carpets, dirty?  just spray it down
Storms want to come to Hawaii for another 40 days,
I say, BRING EM ON!
(the only problem is you have to do research on fading,
and stick with black, because the off white looks BUTT UGLY
when used on an exterior)
