WHAT ARE YOUR THOUGHTS ON SPENDING EXTRA FOR THE GMC 2500HD DEISEL, OR A REGULAR 1500 WITH A 305 V8 TO PULL THE OCCASIONALL BOAT AND TRAILER. KEEP IN MIND I DO DRIVE A LOT. PLUS THIS MAY BE A SERVICE VEHICLE WHICH DOES A LOT OF STOP AND GO. I DO AT LEAST 90KM PER YEAR ON MY VEHICLES. 20 GRAND IS RIDING ON THIS QUESTION.
