Wait a minnit, let me get this straight;
You are complaining that a 3/4 ton (1500 lbs.) truck only has a payload capacity of 1 1/4 TONS?
So, go get a 1 ton dually that has a payload capacity of 2 tons. YES, you CAN use a dually for a daily driver! I been there, did that.
Based on personal experience with that old truck ('94 dodge 3500 CTD dually), I agree with Marty; PAYLOAD is the ONLY important number. GCWR is basically a "happy with performance" number. I discovered that my rig was 3,180 lbs OVER the GCWR, but UNDER all other ratings. It did just fine going over the Rockies, the Sierras, and the Cascades.
Go trade for a one ton truck. SRW if you must, but I liked my dually!
Note: My old truck was registered for a GVW of 14,000 lbs (that is, VEHICLE weight, not COMBINED weight). I picked that number because I knew I would never exceed it. I was right!
