Yes the word is comfy for our Chevy. The Ford 350 was a fine capable truck mechanically and had 300 more pounds for payload. I don't like driving over the total allowable GVW, thus the reason for going 3500. The Ford was an extended cab and 8 inches shorter wheelbase, which was nice for turning in tight spaces. The Chevy 3500 is a crew cab, back seat made more room for our dog in a soft crate and camera gear. We also had the maxed out LTZ model, luxurious for us! We realized we were going to be living in the vehicle for months and the extras paid off. Leather was easier to clean compared to the cloth in the Ford.
All in all after driving both, they stack up evenly for the work(holding the weight, driving stable with no sway in huge winds, etc). Gas mileage similar. The trucks performed fine with out putting on any after market suspension.
The big difference was the ride on washboard roads, highway imperfections and rocky dirt roads. Chevy's front end was much more comfortable on the kidneys and spine, less jarring. The ride was one of the main reasons we switched and while were at it we went for a little more room and cab accessories. Chevy was a bit more pragmatic in their cab design with the options and features.
We did notice more Chevy/GMC's 2500 and 3500 trucks in the Yukon and Northwest Territory, much more than Ford or Dodge trucks. When we got back to Montana, WYO, the U.S. states we saw more Fords and Dodges on the road. I can only guess it is because most all the 1000's of kilometers of roads are dirt, ?? advertising in the U.S. ?? work tough trucks"?? cost??
I have driven all the top 3 brands of trucks(during my firefighting career). When driving 100 miles a day on dirt roads through the years they all would eventually break down mechanically and physically shake apart, even fall off the frame. In those conditions I would rank the longer lasting as; 1st Ford, 2nd Chevy, 3rd Dodge.
When it comes to a 1 ton or 3/4 ton truck for personal use I believe they all would do fine. Maintenance is the key and if comfy and capable is wanted and you aren't married to a brand, I would go GM. Most people don't drive that much dirt and rough roads daily for the year.
Not sure yet where the next long trip will be. So many choices. We definitely want to go back to more of the North. Maybe Yellowknife and boat up to find Narwhals and insects are frozen
