Both the current 13' and 16' Scamp packages come with 1.9
cubic foot fridges, priced separately at $603 USD, so Charles
suggestion is perhaps a better alternative since small fridges
can be had for less than $100 USD at Best Buy or Sams.
Scamp also offers a 4.6 cubic foot fridge
upgrade on its
16' ers for $250 USD more or $850 if bought separately.
You would need to buy 17' Casita
to get a bigger fridge.
I would talk directly with Steve at Scamp, since he's the go
to person there on parts, before making a final decision.
BTW, I'm in the process of moving from San Antonio, TX to
Mesa, AZ. I live in the Olmos Park area near Trinity
I plan to purchase a 16' Scamp with side dinette in the
near future after carefully reviewing all the fiberglass choices
in the market today. Scamp strikes me as a rock solid unit.
