The Heavy Duty Payload Package has not been discontinued. You can find detailed information on it if you build and price a XLT F150 with 8' bed on fordvehicles.com The package is easily found if you search dealer lots on forddirect.com I just did a test search. The first dealer I looked at had two 2006 F150's supercabs with the HD package. So they are not too hard to find if you know where to look. If you want aftermarket wheels, they are available from Centerlinewheels.com who has some of the nicest wheels - about (15) 7 lug wheels to choose from. The trucks have ugraded springs and frame and the ride is smooth like an non-HD F150. It's a good option for those who need the cargo space, and extra payload but don't want to more money on a Super Duty F250. Another reason - it has a better ride and a nicer interior than the F250. I also have the HD and I don't have the vibrations like some people with the regular F150's have been experiencing. So that may be another benefit.
