Maybe so, depending on what you have now? If it already has the load distributing hitch platform (2" square receiver under the bumper), then all you need is the proper hitch head and ball (hitch balls come in various weight ratings themselves and I'd be sure to get one rated for 8,000 pounds if it were me).
I used to do lots of trailer towing, but don't anymore, so when I bought my '99 F150, I just wanted the Supercab and fuel economy (along with tilt wheel, cruise control, air-conditioning of course), so I just have the 4.2L V-6. I've only had it a year, and it does not have the hitch platform, just a 2" ball on the bumper and I've not yet hooked a trailer onto it. But on the bumper, it says maximum trailer weight 5,000 pounds and maximum tongue weight 500 pounds. If or when I go back to RVing, of course, I'll promptly trade trucks. /forums/images/graemlins/laugh.gif But in the meantime, it's a great one for my use.
Sounds like your rig is pretty well set up assuming you have the brake controller to go with the trailer brakes. /forums/images/graemlins/smile.gif
