Great advice so far. If you’re really set on keeping your truck I would do several things to it. Upgrade your p-spec wheels and tires with a good light truck wheel and tire with a Load Range of C or D, install and extra set of leaf springs, and a heavy-duty rear sway bar like those made by Hellwig. Your truck will handle the extra weight much better, but, as you probably already know, won’t officially raise your payload. I would do this before buying any Lance 650.
