Well after much research I went with the "Thule bike rack system".This fits on the top of the roof of the truck.Will be able to carry 2 bikes.The whole system-roof rack and bike(2)racks,locks are included also was $400.It sounds like a lot of money and you know what???IT IS OUCH.But for us it was the most secure.I have a front mount hitch on the truck but that is where we carry our generator.The hitch on the back of the truck-I wasn`t comfortable with the turning radius.And the ladder rack was just about a 50/50 split.Half the people liked it their and half didn`t.
I my orginal post I stated I didn`t want my mountain bike costing me a mountain of money-well its not a mountain but its a pretty good size hill
