I run a 2WD 2008 Silverado and pull a 22 ft Starcraft Islander hardtop. Most of the time I have no trouble pulling the boat out of a launch. One time on a wet steep ramp it was a no go. I was able to pull out by seating some heavy hitters on the tailgate and angling up the ramp. I may have been able to get out just angling up but the guys were there so I added the ballast. I recently added two tow hooks to the truck and carry a pail of cat litter for traction. I also carry a recovery strap. I never have had a problem at my primary launch site, but all sites are not created equal. It's nice to have the 4WD but I don't regret not buying one. I got the tow hooks on eBay for around $30 and the 3 inch 30 ft strap cost $25. I may not ever need the hooks or strap. I hope this helps with your decision.
