Last time I weighed, I was about 10,500#. GVWR is 9900. That was on a 5 day trip without the dogs. I have both dogs now and I'm on a 10 day trip; I wouldn't be surprised to see it closer to 11,000. No tire is overloaded and I am anal about tire pressure, but I still wish I had a dually. Oh and my camper is a Lance "Lite" 815--you know, the one they said would work on a 1/2 ton truck. It overloads my 1 ton SRW.
If I did not already own my truck when I bought my camper, or if I were buying another truck, I would only consider a dually for either 5th wheel or truck camper use.
