I have a 2003 4Runner SR5, V8, 2WD. It has the factory hitch. I am considering buying a motorcycle carrier that would accommodate two dirt bikes, maybe a 125 2 stroke and a 150 4 stroke. The carrier I'm looking at is Versahaul. I believe my hitch has a capacity of 500 lbs. The Versahaul would be about 120 and figure the 2 motorcycles combined would be about 400, so total weight on the tongue would be at least 520. But, considering that the carrier will extend out past the hitch, the weight would actually be more (consider the fulcrum / leverage). So, my question is - would you advise me not to proceed with this? I want to get the bike carrier because it would take up less space in the garage, no license plate, no ad valorum, etc. But, I don't want to screw up my 4Runner or make it unsafe to drive. Or, how could I go about increasing the tongue capacity of my runner? THANKS!!!!!!
