Custom Built Insulated Cooler Boxes ACR Caravan Repairs can custom build an insulated cooler box to suit your needs. Made out of insulated aluminium it is both practical and surprising light. A must for anyone who likes entertaining with lots of guests. All you need to do is add the ice and drinks! In addition to being a great cooler, it can be utilised in mobile homes/horse floats as seating in the dinette area (removable covered cushion included) and then moved outdoors when you arrive at your destination for outdoor seating and cooler usage. On the back of the truck these coolers boxes can be used to store tools, feed or holiday gear when not in use.
