The MugWump 22 is the evolved version of the MugWump 21.  Sam wanted “an Airstream -type trailer for the water.”  A boat that could also serve as a travel trailer on the way to your cruising grounds so you wouldn’t need to stay in hotel.  Essentially a tiny home for both land and sea with an enclosed shower and head, galley, 3 berths, and a back porch.  And all this is towable by a midsized SUV or 1/2 ton pickup truck. The study plans give you 4 drawings of the boat including accommodations and a drawing of her on a trailer behind a pickup.
