I just weighed our F350 King Ranch LB SRW (8100 lbs.) and Wolf Creek 840 fully loaded, gassed up, water tank full, with the two of us in the front seats. Taking for granted that the scale (Idaho Port of Entry) is accurate, it came in at 11,740 lbs. That is heavier than we usually travel since we don't always fill the water tank (35 gal.), but have just enough to flush a few times. Is this a surprise to me? No, I expected that weight.
The truck has upper and lower StableLoads and handles well enough for my comfort. I also hold a CDL and drive lots of different stuff at work. The rear axle weighed well under 7000 lbs. and the front was much less, so I don't worry too much about maxxing out my load range E tires or factory rims. Tire wear is accelerated versus normal wear but I don't feel it is too excessive.
There are campers that work on SRW trucks, especially with some suspension aids. Best to go with a 3500 or 350 series truck to have the benefit of upper overload springs. I preferred the long bed for center of gravity stability and better tracking on the highway. It is a pain in some small parking lots but manageable. Do I wish I had a dually? Occasionally.
What works for me and my wife is not what might work for your situation, but there are ways to cope with less camper and less truck. Be sure you are into the more minimal accommodations before you pull any triggers. We really enjoy the ability to fit into almost any campsite and parking space. We also like the ability to have a small footprint with as much comfort as possible. Taking off at the drop of a hat is fun and stimulating. We just got back this afternoon from a one night jaunt that we took just to be "out and about."
TC's are great for getting somewhere more remote, even if it takes a bit more skill to drive it. They are also easy to maintain and equip. Be sure to stay light with the rig and everything you put into it and you will not be too heavy. Leave the anvils at home.
Find others in your area with TC's and engage them in conversation. Compare what they say with the pro and con crowd here and find peace with your gut. You'll be okay. We are.
