Airstream has recently come out with awesome stainless steel upgrades for the hot water heater, furnace, range exhaust, exterior shower, and water fill.  These add a nice pop to the outside of the trailer, making everything more cohesive.  They offer two styles for the water heater and furnace, with rivets or without.  These two styles are purely cosmetic and we have found that customers are equally interested in both.  Before your next big trip or weekend getaway, check these out!
