Has anyone fitted auxiliary fuel tank(s) in an A35? I am getting really tired of carting 5 gallon containers and would like to install some additional tank capacity so that I have at least 50 gallons aboard. The 24 gallon standard under-cockpit tank is in a good spot but is too small. I get around 8.6 nmpg. 60 gallons would cover 500 miles, more or less, which seems like an acceptable range. Am considering raising a main cabin berth and mounting a permanent low profile 35 gallon tank there which would keep the weight low.
