New member looking to purchase first travel trailer

pay attention to tongue weight. id bet dollars to doughnuts you run out of payload before you hit towing capacity. Remember payload minus occupants minus equipment (including heavy weight distribution hitch) minus fuel = whats left. my WJ is rated for 6500 lb towing but only 1000 capacity. I am at full capacity towing my 3600lb trailer after im loaded to camp. no way I could do it loaded for full timing.
