I don't have the Dolphin, but a New Horizon that's a 1986 model. It's approximately the same as the Dolphin. It has the properly beefed up rear axle that someone had mentioned a recall on. I've owned it for about 8 or 9 years now. I've loved it as I can go camping on my own and not worry about being exposed to the elements or crazies. (I can always just get in the front and drive if someone tries to bug me while I'm inside!
It has taken me to Yellowstone, twice, the Grand Canyon once, Mount Rushmore once, and numerous trips to the west coast for camping on the ocean.
It has had to have a couple of repairs along the way... new alternator at the Grand Canyon, new clutch last year, and a troublesome oil leak which apparently manages to work its way back about every 4 years. But all in all it's a good little rig for one person. I am, however, looking to buy something just slightly larger this year as I spent 2 weeks on the Olympic Peninsula last fall and got just a bit confined feeling since the weather wasn't cooperative enough to let me sit outdoors as much as usual. So since I eventually would like to possibly retire and use the motorhome for even longer times I want to upgrade the space/floorplan for more indoor comfort.
Still you can't beat the gas mileage in one of these little rigs, and I know I'll miss that if I do buy something bigger.
Enjoy and ask me more anytime!
