Im not sure what your cost factor is Dog King but if I had the money to put in a custom cart, would be a thermostatic cooler..I found a site that I am going to buy from in the next month or so so I can have more perishable products that the HD wants a temp control compartment.

Not cheap but cheaper than stainless steel for $1,500!

That will take you to there biggest 12v cool 84 quarts, that will hold more than 80 cans of soda or store cheese and other items that need to stay in a constant temp to pass HD codes. It will go down to -4 degrees..and in less than 12 minutes…so a hell of a good product and it will let you sell more food items if they see that on your cart as it’s considered a temp controlled storage

Like I said I am getting one and in a few months later another..then I should be set and plus you can write it off on taxes… I hope everyone is paying taxes!
