I'm with Grumpy's suggestion...sell your long bed and upgrade to a short wood bed...
A wood bed adds so much more value...
I suggest you reach out to Gr8-68 on this board for pricing on wood bed...he hand makes and finishes each board...sweet...
As far as the concern about a wood bed getting some use...why not use a bed rug when you have a load on board...they are available from several suppliers...and not that expensive...
