Safe location for undermount propane

yep you bought the wrong tank, you need a lower quadrant tank! no way to make that tank work unless you can put an elbow on the fill pipe to angle it down, and even then the gas guy will bitch because it will be hard for him to get the hose on there - this is someone elses link i saved because i am thinking about a tank too. http://www.pplmotorhomes.com/parts/lp-gas/rv-propane-horizontal.htm

from years of repairing semi truck/trailer air tanks, and those are lighter tanks, your bolts are too close together and should be spread out more because vibration and potholes will produce a strong pendulum effect that will cause the tank to want swing back and forth if any of the bolts loosen up, eventually destroying the cross brace and maybe causing the tank to drop.
