First, take it to a scale and weigh it. Get weights for each axle and because you have a smaller rig, getting weights for each wheel might be a good idea.
Second...compare your weights to both axle and tire load ratings for your rig.
If you are over either, then you need to lose some weight. Or in the case of tires and wheels, you might be able to upgrade.
If your axle and wheel weights are within limits, then I would not worry too much if you are 200# over on GVWR only. You will be in the same group as many of us here....just drive with care and enjoy your rig!!
