This question comes up frequently. You'll find that we all love whatever we've got, and are pretty impressed with what the others have. The differences between the three are pretty much preference as regarding quality (late model
Burro excepted, where they had some problems, as I understand it). Any of them should last a lifetime if taken care of. They vary somewhat in construction.
Scamp is a
fiberglass top shell with a wood floor deck.
Casita is a full
fiberglass shell, with a wood deck inserted onto the
fiberglass floor pan. These two are single wall construction, finished in Insulite or carpet, depending on the age of it.
Burro is double wall constructed, so you have a glossy finished interior surface. It is somewhat stark but offers some real advantages, too.
Due to these construction differences,
Scamp comes in the lightest,
Casita slightly more
weight due to the fiberglass floor pan, and the Burro is the heaviest, due to the double wall design.
Generally speaking, we suggest buying whichever ones you like best. If you are in the south, you'll find Casitas but not too many Scamps. The opposite is true if you are in the north.
I didn't ask if you plan to buy new or used. If new, DON'T give Burro any money until they deliver you a finished trailer. They are essentially out of business, but nobody seems to have told the sales department. As for Casita and Scamp, both seem great to work with.
If you are buying used, both Scamp and Casita spawned from
Boler, along with many other brands --
Eco, LoveBug, Acorn, and numerous others. Don't forget to include those in your search.
