Since we're just spitballing here...
A MH one foot longer than the biggest one ever built. A crew of six to take care of my every whim. Two blonds, two redheads and two brunettes whose ages add up to 126. A crew of professional drivers to drive my MH and take care of repairs. But they'd travel in a separate MH, along with my professional chef and a butler. A semi to carry my toys. A corvette, a rolls and a Harley.
My own private FHU campgrounds in Alaska, Wyoming, South Dakota, Arizona, Florida, South Carolina, Maine, and Las Vegas.
I'd probably just spend the rest foolishly.
