Trucker's wife wanting to get him a dc to ac inverter

My trucker hubby is working for US Xpress and has to purchase his own inverter that they install. I'd like to get him one that he can run a mini-fridge and small microwave or food heater and anything else that could be used for a warm meal when he crawls back into the truck after being in the trailer unloading it in freezing temps at various stores. It has to be 30 degrees or lower for the sleeper heater to kick on. Could someone recommend a decent brand? I'd like at least a 1500 watt.
