How hard to install transferflow 56 gal on C/C

[cowboywildbill]

Has anyone installed a transfer flow 56 gal replacement tank with the large filler neck into a 3500 D/max allison crewcab dually? I also have a B&W gooseneck flip ball hitch, I don't know if that matters or if it hinders the swap. Would appreciate any pointers from anyone that has gone this route. Thanks.

I had a 45 gallon tank installed there recently with the high volume filler. I can't say enough good things about them and my experiance with their products. I suggest that you contact them for accurate information about your installation.
