  • Great!!
I like it can’t wait to get out and use it this summer at its full capacity.

  • It works
Shipping was quick - I put one in my 32 ft grand banks yesterday - 40 gallon with fittings- it is a plastic tank no more no less - no whistles or bells. If you need a tank upgrade check these guys out.

  • It’s exactly how it was advertised
I think that the plastic is a little thin for my liking. I hope it last.
