Am I forgetting anything???

You will like the 865, I know we do and it does have all led lights inside and out. I had my dealer install my agm battery instead of a wet cell mainly because it is a real chore to access the battery and here in Arizona you have to constantly monitor the wet cells during the summer months. I use Stableloads and like the way they work, I'm sure air bags will work just fine for you also. I started with a 2008' Dodge Power Wagon 2500 and bought a Ram 3500 a year after hauling the TC with the Power Wagon. The PW did okay hauling the 865, but with the Ram 3500 you hardly know it's on there. The 2008' PW only had a payload capacity of 1800 lbs and my 865 wet and loaded is 2,600-2,700 lbs. I had added rear overload springs, rear stabilizer, Stableloads and Rancho 9000's on the PW to enhance the handling while the TC was on it. I had my dealer install a 100 watt solar panel and controller, it was $250 less than Lance and it is definitely a worthwhile addition. I also had my dealer put a 7 pin plug on the Lance power cable so I could plug it into my 7 pin receptacle in the bed. We have had the 865 for 2 years now and are very satisfied with our setup!
