ok, so been searching like crazy for 43#/10 gallon aluminum propane tanks, and almost went ahead and bought a couple new... ugh, glad i didn't. Tinbeater gave me a 43# spare he had to use for mockup, and once i got it in the rig, it became aparent how freaking huge a 43 is, and maybe why a few peeps don't run them. My tanks are going to sit in the small area behind my third seat. That area also seemed much larger until i tried to fit some tanks in there. So, had to move the damn thing forward again... ugh.
That 43 is just sticking way too far out the back for me to feel safe. On a backwards roll, i can just see a sharp rock puncturing it and then a spark from the chassis against a rock, and we are all crispy bacon.... no thanks.
The 33# sit ok sideways, but that bottom tank will be near impossible to get out once there is plate on 3 sides of it, etc.
