Purchase the larger
battery. I also recommend the heater. We picked up our 13'
Scamp in Backus in July of 2012. Essentially, it has everything except the AC and
awning. We did have the roof prepped for AC, mostly for re-sale purposes. Our
Scamp is used primarily to
escape the heat of the Phoenix area summer. We head to higher ground where AC is not needed, but a bit of heat in the wee hours often is. A 10'x10' EZ Up makes a great covered porch. I love the clean and aerodynamic look of an egg roof free of add-ons.
