I can't speak to the Camry on this one, but my 2004 Acura TL (turned in for a Jeep which was then turned in for my TCH) had a 1000 pound weight limit which I exceeded regularly. I would drive myself and my three friends around (all of us tip over 250) along with a trunk full of emergency gear, and I never had an issue due to the weight OTHER than finding that if I parked over a curb or parking bumper while driving alone, having the four of us in the car when I backed out would cause the TL's ground effects to scrape along the top of the curb. (This became a never-ending source of amusement for my friends.)

I imagine it might be a similar thing in the Camry, but the TCH has a higher ground clearance to begin with, so you'd probably be okay.
