I have had my Horizon two years now and first word that comes to my mind is versatility - it excells at that. Can't beat those side boxes, just add some plastic cutting board material and you have a built in shelf to work from. I located my fridge in the back of my 06 Tundra secured with Macs tie down rings on a sheet of plywood that is covered with a re-cycled tire mat material that is way durable and dense. I have Equipts National Luna Portable Power Pack for my big Odyssey 2150 battery. I went backpacking in the White Clouds last month, was gone 4 1/2 days with Lynda and my dog, with highs in the upper 70's to low 80's and lows in the upper 40's -low 50's and was blown away at the end of the trip to see the ARB fridge LCD displaying 39F - best IPA I ever had followed by cheese an crackers. Also like my fridge in my truck, as I can leave the Horizon and go out wheeling in just the truck and get the batteries charged up.
Last month I sold my EA 1800 and just now I'm mounting up a Globetrotter. Only myself, my wife and dog and usually just myself, so the Globetrotter is sweet with the little room attached to get out of the weather. Seems that I'm always pulling in some where just as it starts to storm, and with the GT as soon as you open it you have a roof over your head to get oriented and get the rest of your kit set up.
