The Host Mammoth is the largest truck camper in production. It has three slides and weighs over 4000 pounds and requires a full size dual wheel truck. To truly appreciate this camper it must be seen in person but the Host website is very informative. Here is a small list of items that set it apart from most truck campers: 2500 watt onan generator, king size bed (still in original plastic), 65 gallon fresh water tank, 2 flat screen TVs and electric fireplace.  The separate bathroom includes a large shower and separate toilet and sink (not combined like many truck campers). The kitchen has plenty of cabinet space for extended trips and has a large 2 way fridge freezer, convection microwave, 3 burner gas stove and a double stainless steel sink. It also has a large couch that folds to a bed with a dinner table that can be lowered to a coffee table. There is plenty of inside closet and drawer space but the basement storage (45 cubic feet) with a full size slide out tray is amazing. We have made some upgrades, including: larger than standard air conditioner, tinted windows and 2 fantastic fans. We purchased this camper new and it has been always stored inside.  The exterior is like new.msrp for this camper was $65000 current similar units are closer to $ 70000. These are pricey campers new and clean used ones are hard to find. Thanks for looking if you are interested and have questions please give me a call. Thanks again joe (919)669-five nine one four
