You don't say what TC you have. Did you weight it personally? I'll bet it's much heavier than you think, then add all the weight for gear, food, water, etc and you'll be 500-800 lbs heavier.
I'm no expert, but it is not safe to put that much weight on a 1500. This is exactly one of those occasions that you should have consulted this site BEFORE buying.
If you get into an accident, your insurance may choose not to not cover because you are WAY over weight.
Weigh your rig and then get back to the forum for more appropriate advice.
