My TC loaded and wet is right at 4k. It is right at the trucks payload rating. Probably my truck camper rating ddodad is right where is yours is. I do use stable loads quick connects but I had used the camper without them for sometime with no problems. The stable loads did give me just the bump I wanted in support to get rid of most of the sway issues. The nice thing about them is you can engage them just when the TC is on. I think you will probable be heavier than 3k loaded, they usually fudge those numbers down. I also tow a 3500 pound boat behind my truck with a 30 inch extension. No problems. Towing the boat is when the quick connects really paid off. My 4k number includes the tongue weight of my boat trailer. I know I got a little disjointed in writing this but I kept coming up with more things to say!!!:)
