A lot of good replies here. For me, I have stayed away from pickups and trailers. They take 2x the maintenance, tabs, d.o.t. inspections, ect.. They do cut short corners backing in on the lighter side, but can be a bear to load of you don't have power (winch or anything to help you load or tilting to unload). A single axle truck (in my opinion) is the way to go with a little Detroit diesel (excellent mileage, dependability, economy motor) and you can load it up nice (6-7 ton) and still get about 16 to the gallon in a medium duty truck. Maintanance is a tad more but repairs are very seldom. You have live hydraulics and can winch like none other using the motor for the power. these trucks are pretty cheap and cheap to operate. Keep your mazda for the light runs (pickups) and you have your bigger truck for heavy pickups and getting the bigger checks at the scale.
