All my gasser racing buddies say you have to have a gas golf cart or it will make your trailer way too heavy, but then again they're not stuffing 7k trucks in their trailers either, I'll bet the golf cart difference is about the same as whether the stock seats are in the race truck or not! With a diesel race truck and diesel tow rig, keeping the golf cart electric just means one less thing you need gas for! I use an electric scooter for my pit transportation.
