If your Scamp
is reinforced for it, roof A/C is simplest and gives the best circulation. It's also fairly noisy and transmits vibration through the shell. Price is likely similar to the CoolCat.
Inexpensive alternative is a window A/C, which can be permanently mounted in a cabinet (requires a largish vent cut in the shell and DIY engineering of baffles and condensation drainage) or temporarily through the rear slider (remove for towing, requires a filler plate to cover the gaps).
Note that the CoolCat will also require an exterior vent cut in the shell.
