Not sure which model might work for you, but I bought the RDS brand (42 gal tank/tool box combo) some years back. At the time, I wasn't sure if I was just splurging on an unnecessary investment. Now, I can't imagine living without it. I am very happy with the RDS brand. I installed it myself just going by the instructions and it has worked flawlessly. Northern Tool had the best price online, shipping was a breeze, and I saved over local vendors who wanted more and charged sales tax. Good luck.
