If you raised your top mount in the front and measured up/down travel, that is what you should get. Most are reporting 12-15" travel shocks working best after this mod.
Inboarding the rear is not bad, its just not ideal. If you can make a mount that is vertical from the axle, which makes the shock completely vertical, then perfect. But sometimes the shock needs to be tilted at an angle to utilize all of the suspensions travel without bottoming out on the shock.
Jeep Wranglers are inboarded, just not at an extreme angle. Don't go to the center of the bed when inboarding them, only go in as far as needed. The closer to vertical a shock is (or closer to the suspensions "line of travel") the better. Same goes with the front shocks.
For a daily driver, I wouldn't inboard the rear shocks. They wont work well enough to drive on the freeways around here, too bumpy. But if the truck sees more articulation type travel, then bumps, inboarding them is easy and effective. IMO
