The Coleman Igloo will sit in the passenger seat if you decide to leave the seat in., just bungee a cord around the seat to hold it into place. Do make sure you get the 700 watt microwave, higher wattages pull too much draw. Husband also has an ice maker from Walmart that he uses, great when you are stuck at a shipper/receiver. Thinking about getting a coffee pot like the smaller Keurig, it uses pods or you can use your own coffee in the washable filter pod. Husband doesn't have the LW now, has a Pete with the built in fridge, but still uses his cooler. The Pete doesn't have much more room than the LW.
