Hi everyone, I have an '88 gmc 1/2 ton with a 3 inch lift kit. Am I totally crazy in wanting to put a camper on it? I'm new to this, so forgive my newbie questions. I've been told I can't go much above 1500 lbs with a normal half ton, so I wonder what the lift kit does to this? Also, I've seen 'helper leaf springs' for sale on the internet, which fit inside the regular leaf springs. example here -- http://www.avirtualmall.com/discount/947098.html These claim they increase the capacity of the truck bed to 2500 lbs. Does anyone know if these work, or if they would be useful in my situation. (what makes a 3/4 or 1 ton different anyway, heavier leaf springs and shocks? bigger engine?) I'd love to have a heavier camper, if they would work. Thanks for any advice you may have!
