Your suspension will be exponentially more expensive if you want super streetable performance with 37s over 35s and obviously the more height you run, the more issues you'll have towing a trailer comfortably (and the more challenges your kids, wife and labrador will have clambering in). If you want "big tires and low lift" aka
@Broski style you're going to need to get comfortable cutting up sheet metal, which seems like it might be more than you want to commit to at this point of the game.
You have 35s. Wheel them. You're not going to see a
huge difference it capability with 37s and if you haven't wheeled the rig, it's better to learn your capabilities and become an amazing driver while you're a little closer to the ground and have a little less leverage on your driveline. Delta 4" arms and Dobbie 2.5 VVTs (which will net you 4") would be where I'd go first. May want to run the Dobbie 3" VVT in the rear (which netted me 5, empty) if you're going to run serious weight back there. When I added my drawers I had to add a 1" spacer to the rear.
