I'm going back and forth between ordering a GM 3500 and a Ford F350. I'll occasionally be carrying a 1100 lb slide in camper sometimes while towing a trailer with a snowmobile. Not going to do any real overlanding or off-roading but I'll be on some dirt roads and FS roads (though not with the trailer!)
I'm not a mechanic and don't have a lot of real world experience with newer trucks; but I like that the GM IFS is supposed to provide for a better ride and I'll probably be upgrading stock tires and shocks anyway. My wife's daily driver is a Colorado Z71 Duramax, which is a great truck and has been awesome in the snow and rough roads out here. So I'm leaning towards the GM. However, at my job as a Paramedic we've had Ford chassis and GM chassis on our medic units that have been driven hard. Over the years the Fords have proven to be much better rigs in performance and durability.
Anyone have opinions or input?
I've run GM trucks for years, not so much that I'm "brand loyal" but because they have earned my business. The trucks are very reliable, ride nice, handle nice, etc. My work trucks are used in my electrical contracting business and they haul and tow heavy a lot. I often take them off road to reach remote job sites. I put close to 20,000 miles a year on my DD truck, all of it hauling, lots of it towing, and I'm off road several times a month. I have never had any problems with the IFS in any GM HD truck. I had to replace a CV joint in an '87 Blazer but that's about it. I've driven some Fords with the solid front axle and they handle like crap on the highway.
My current 2005 dually that I bought new has 298,000 miles on it. It used to carry my 4,000 pound TC while towing my 4,500 pound boat with my family of 4 in the cab. I've carried that camper from VA to FL, MI, and CO and it did a great job, even being about 1,600 pounds over GVWR.
