I currently own a 2003 chevy 2500 HD, My former truck was a 99 ford F-350 4x4 reg cab dually. I did not see any real insurance cost diference between the two, the Chevy was actualy a little more than the Ford, probably because it was 4 years newer than the Ford. The yearly non commercial plates were a different story, around $108.00 yearly for tags back in 02, wher the Chevy is around $83.00 dollars in 08. In Ohio, some insurance companies will not write a non commercial policy for a 1 ton with out special approval from underwriting. Back when I had my Ford, As well as when I first bought my Chevy, I was insured through Nationwide, And my agent had to call underwriting and send pics of the truck, and I had to sign a draft saying that the truck was not to be used for commercial purposes. In the end, they did end up insuring it non commercialy for close to the same amount of money as the Chevy. In my opinion, unless the 1 ton would offer me a true front axle upgrade [ in the case of a 4x4], like in the mid 80s to mid 90s Ford F series where the 250 had twin I beam and the 350 had a dana 60 straight axle, I would,nt bother with the single rear wheel 1 ton. The heaviest thing I have had in my 3/4 ton was a apprx 3500lb pallet of brick pavers from Home Depot, along with the 500lbs or so worth of chains, tools, boots, hitch receivers etc that I always carry with me. The 2500 HD handled these just fine, it squatted a little below level in the rear with the load centered over the axle, but just a little. The tires on the other hand, at the time, 10ply [ load range E] 265-75-16 Firestone Transforces inflated to 80 psi, looked to be about at their practical load limit. Having traded a 1 ton for a HD 3/4 ton, never once in 5 1/2 years have I ever regretted not getting a heavier truck, and never once would I ever consider getting a half ton, because I would be disappointed with the way it hauled and towed, based opon my personal needs. If I ever did feel the need for a 1 ton again, I would just opt for the Dually instead of the single wheel to ensure that I always had enough tire capacity.
