Thanks for all the wonderful advise and pics. My experience on beach camping is like others have said, 'nothing like camping on the beach'. There is just something about sitting by a fire, watching the sunset over the ocean, hearing the surf crashing, enjoying your favorite beverage (responsibly) and the smell of a 16oz porterhouse and baked potatoes on the grill. Ahhh...
I had a 2500 suburban (when tent camping) buried to the axels on a hot summer day at Carolina beach. God sent me an angel in a F150 and he pulled me out! I paid him $20 because that was all I had on me. The best $20 I ever spent. After that I always air down with the Suburban. I sold the suburban and now have a (city boy) pickup, 2006 Avalanche. No need to air down, floats right over the sand. The only problem is that we are still tent camping.
Yes, time to get rid of the tent and the Avalanche and go for the TC. No TC will fit the Avalanche. Actually I did find some specialty rigs to fit it but they are costly and not around here (NC). As for corrosion, I live near the ocean, so it is just something that you have to watch for. I would not let it stop me from going. If I lived my life protecting every investment that I ever made, well... I would not be living (IMHO).
But in regard to my original post, looks like most favor a 3/4 ton or larger. Most favor gas not diesel. I am still on the fence. A guy at a TC dealership swears that a F150 with a matched TC will do fine on the beach (if you air down). Of course he has motivation to say that. So the question is, does anyone have 1/2 ton, with matched TC that does beach camping? Forgive me if you already posted affirmative to this question. I am still trying to go through all the posts.
