I had a 77 Foretravel, 440, based off a D-300. Should have kept it. Beautiful, all new inside. Point of use hot water, bedroom, bathroom, kitchen, new fridge/ freezer, new carpet 2 roof top a/c units, she was older, but rehabbed and clean as heck. Never used Her, a Family in Gainesville needed a home so I sold it to them. Been sitting for Years, they drove from Zephyrhills to home.. unfortunately, I didn't look at the 727 that close, but the sparkplugs drove me nuts....Peanut plugs.... took 2 trips to the parts place to get it right.( didn't think I'd have to take one with me...)
