Nice ram. Mine is a 92.
I took my hitch apart and flipped the receiver part upside down and welded it to the top of the crossbar. It looks like the factory should have done it, making a very nice departure angle.
I think you might want to reconsider the amount of weight you are hanging off the back end. These pigs are pretty tail heavy to start with and adding that much to the rear isn't going to help your hill climbing or your towing any. It especially makes backing down a steep hill a problem, as it unloads the front tires too much and makes the front want to slide sideways.
If you decide to gear it, you can buy thick Dana 44 gears and keep your 3.23 carrier, add a lunchbox locker and you are set.
I would keep that rear swaybar if you plan on a roof rack and flexy rear springs. You might like it since Dodge decided to inboard the rear shocks, taking the leverage away which prevents body roll.
Crossover is the way to go, even though I have the adjustable draglink on mine, it's still not very good when you start twisting one up. If you like flex, then look up the spring rate difference between Chevy front springs and Dodge. Almost 300 lbs/in difference in some of them. RC Central is great, but there are tons of ideas that interchange between blazers and Ramchargers.
I'm just over the hill from you, so if you need something I might have an idea where to get it, since I have a couple Dodge nuts in the neighborhood.
