We have been looking for several months at rv's and have decided that the Cyclone 4100 King in the best fit for us . We decided on the toy hauler because we do vinyl graphic's and we plan on taking our business on the road with us when we travel full time . We presently have a Chevy 2500HD with duramax diesel . The sale rep told my wife that if we installed air bags , heavier tires and a slider hitch our truck would handle the 4100 . I have run the numbers and it goes right up to the max of 22000 lbs . My better judgement tells me that is sales talk and that we need to trade up to a dually , but this one is paid for and if it would work for a few years then it would be worth the cost of the upgrade . Would like to have the forums opinions .
