But my tastes tend toward the anachronistic.

I wish we had your water and fuel tankage. The Alberg has a 24 gallon fuel tank and two 24 gallon water tanks. I usually keep two 6 gallon jugs of water and one 5 gallon jug of diesel in reserve. I was able to shoehorn a Vee shaped 25 gallon holding tank through an existing hatch under the bunk. It's usually plenty for two.
