Whats Your Real Weights? Truck and Trailer. The Real Deal

Thanks guys for the replies, makes sense about the oil burner being heavier. This is our first diesel truck, we were pulling the 5er with an under powered, over worked 3/4 ton gasser. We were getting about 3 gas stations to the mile with it, now we get 12-13 mpg depending where my foot is. I picked up a transfer tank, 105 gal, now I wonder if it will overload my steer axle? We hope to hit the road as part-timers in 2011. Again thanks for the help, this site has been fantastic in answering a lot of our questions!
