We all know, spending more money on our truck campers after the purchase is easy. However sometimes it's smart. Two products that I am familiar with and will have installed on my camper were written about on Mikes site, Truck Camper Adventures. The Olympian wave 6 heater can be used as a portable unit or you can install it permanently. The 300-400 dollar cost will be made up in propane savings. The unit also will not drain your house battery like the blower on your furnace will. For all you boon dockers I would think the Oxygenics shower head would be your first purchase. For only 40 dollars this shower accessory will provide more water pressure while using 30% less water. Now if I could just talk Northwood Manufacturing into installing a 12 bottle wine cooler in my 2017 1140 I could store my precious 2 buck chuck at the perfect temperature. Cheers!
