Hello Everyone! Up until recently my husband used to answer all my car questions. He was a wealth of gear head knowledge. Unfortunately, he is not with us anymore. Now I am trying to figure out the things that I never dealt with, such as the true towing capacity of our 2003 Tundra 4x4 with the V8 but no towing package. We have been using it to haul a 2000 lb Viking pop-up, but in an attempt to make my life a little easier, I would like to upgrade to an Aerolite Cub 185 Hybrid camper. The unloaded vehicle weight is 3492 lbs. with cargo capacity being 1508 lbs. If I read the tech specs correctly, our truck is maxed out at towing 5,000 lbs, which means I probably shouldn't tow that camper with it. I'm hoping it's not true! Could help me out here? I would really appreciate some experienced yay's or ney's!
