Does the CA dmv charge weight fees on a terra? I'm contemplating a project of building a "club cab" terra with 93 dodge cummins running gear. My cummins doesn't get much use due to it's size, I rarely need a full size truck and it's too huge to take off-road. Now a cummins powered terra would work off road and have sufficient wheelbase for towing a travel trailer. I pay around $170/yr in weight taxes on my truck! Don't want to do that any more.
