Great older fifth wheels

My wife and I bought our little treasure going on three years now. It's a 1994 Dutchman Duck that is in great shape and came without modifications except for reversing the double axles. We built a new bed frame with storage for clothing underneath, tore out the dining table and benches and put in a half-round glass topped table, added 100 watts of solar panels and a Predator 1600-2000 watt generator. The trailer is 22' and weighs in at 4015 dry, So it's relatively easy to tow with a light Anderson hitch and our 1997 F150 Super Cab Flairside Lariat 4x4. Not fast, but steady at 55-60 mph. Even Carson City to South Lake Tahoe wasn't overtaxing (three adults and 2 dogs, kayaks, bikes and the usual 10 day excursion equipment). Its pretty much all we need for road tripping the west. Our trips this year hopefully will include, Slot canyons in Escalante-Staicase National Monument, Brice Canyon and Zion National Parks, and Four Corners/Monument Valley Tribal Park, in Utah. We've an ambitious trip to the Redwoods of California planned for September or early October.
