By my signature you can note that I pull a rather heavy 5th wheel. We are 24,400 on the scales. This is truck, full fuel, me, full fresh tank, empty rest. Wife follows in separate vehicle. This is enough of a load that any canned tuner is out. Limped my tranny in Colorado. Flat roads was fine. What I am getting at is your truck will be very loaded and don't abuse it. Increased loads over GM ratings means fluids break down quicker, oil, tranny, diffs, etc. Brakes also wear quickly. Need to stay on top of rv brakes will help truck brakes but I go thru a set a year. I went over a year this time and had to replace rear rotors and calipers. OUCH. My truck is stock height and just slightly taller tires. My 5ther sits perfectly level. With your lift, the front will be up, reducing tailgate clearance and more wind drag. I am not a fan of flipping axles. This raises the center of gravity on the 5ther increasing roll over possibility. Never know when some fool will pull out in front of you and you are forced to go with your "home on wheels" where you don't want to go. Times with this (I've had 2) you will regret flipped axles. I am around 3500 pin weight. That's a lot for a 2500. I am very stable. Even in emergency situations. I have a lb cc 3500. You have the same drive as a 3500. It will tow it, air bags are mandatory. Don't want to hear this but I'd lower truck, and install stock or close to stock height tires. The larger tires increase load on engine. Higher final gear ratio. I full time in my 5thr. I travel a lot. Your 2500 towing that much weight will not be as stable as my 3500 especially in an emergency situation. Will be be all right? You have to decide that. I'm not trying to criticize, just help. God bless
