I moved my tanks a little forward then built a rack to hold my 2X8
planks i use to level the trailer, 4 each. Then on top of that I
placed
2 battery holders to hold 2 6 volt golf cart batteries.
It all works well. Oh yes.. I also mounted a 8 inch curved mirror
to the jack so I can see the hitch when I back up.. It sure helps.
