I have a 1978 gmc 1/2 ton for sale...i've towed my buddy's 24 ft travel trailer with this truck and it did great over the pass......very clean interior and very strong running 350 motor w/ under 20,000 on rebuild......has been converted over to hubs and not full time 4x4 any longer. NADA blue book puts this truck at $3700............if interested give me a shout.......chongo469@yahoo.com.or 425-772-7894
