80 #? I was afraid of that, they're obviously heavy, but I never tried weighing one. My truck's GVW is around 15000, and with its tired old 318, I don't like to climb out of Albuquerque with more than 6000 on it. May have to head down to Roswell instead, or just make two trips and buy the additional 40 gallons of gas.
Funny you should metion alternatives Frank, I wanted to use wire lath and imperial plaster, but it would add about 30% to the cost. There's rumored to be a drywall jack around here somewhere that makes the rounds from one project to the next, guess I better go find out who to ask for a favor.
