I have a feeling the Scamp
covers wouldn't fit very well. This is based on comparing a U-haul
(Burro clone as far as basic shape) and a Boler
(Scamp is a clone).
I think the burro
seats are more straight across the back and front, with curved edges, whereas the Scamp
seats are more of a crescent shape with a gradual rounding towards the corners. Here is a layout that shows the Scamp floor plan. The front cushion has a separate "banana" for the curved part at the back of it. Maybe this will help you decide.
