You really should be looking at the 1 ton trucks for a camper. It just holds a little more weight, and can take on extra loads such as a cargo trailer, extra passengers, or you can fill a couple of extra 5 gallon jugs of water for the trip, and not worry about exceeding it's 11,500 GVWR.
Many 3/4 ton trucks are well under 10,000 GVWR. With a curb weight near 7,000 pounds, that does not leave much room for the camper and anything you might want to carry, along with passengers.
Maintenance for a 5.4L F-150 and F-250 and F-350 is exactly the same. Only change is that the F-350 comes with longer life tires and takes more water to replace the coolant in the engine. (larger radiator among other things.)
The 2004 and earlier F-350 SRW only had a 9,900 GVWR, so it does not need to follow a 'truck route' designated for trucks over 10,000 GVWR (back in 1965, it took dual rear wheels to exceed 10,000 GVWR, and go up into the class 4 truck size. Now a 2005 and later F-250 has a 10,000 GVWR, while a normal SRW F-350 will come with up to about 11,250 or 11,500 GVWR is standard now.
F-350 dually is around 14,000 GVWR, or cargo rating around 6,000 pounds!
GOod luck,
