i'll offer up a pair of bad ass franklin edition drills that have been converted to shoot boolits
if you add up the value of the benji's on the guns, then the trade is heavily in your favor
stick em in storage if no one needs them.
when you go to sell/trade the truck they'll be there in good shape. dealerships won't give you any extra for the weathertechs and you could sell those used for a decent amount.
that's what I've done with mine....sitting on top of the stock z71...
