Great platform to start with. Almost identical to mine.
Since you already have purchased the lift, I can't really steer you away from that, but I have went round and round with what mods to do to mine, and I believe that a high dollar suspension with great shocks, for me means that I push the truck past its limits and end up breaking/abusing more parts than if I would have just stayed nearly stock and babied the truck a little more.
That theory is not true for most folks, but I just went with leveling budget spacers and Bilstien shocks to get a little more clearance and a firmer ride.
I would look into Aluminess Bumpers and get any and every bit of under body/drivetrain skid plate you can get, rocker panels also.
Are you tent camping or sleeping in the topper?
Here is my Dodge, hopefully you stay motivated with the build. :ylsmoke:
