Relax. You will work your way through it. Yes, like other RV issues you may have to throw more money at it but it may be relatively painless in the end. Im a mechanic and I knew before I hauled my used rig home that it would need lift. When I hooked up I thought oh no does it ever need lift.
It all comes down to two things, rail clearance and is it sitting level enough for YOU. The simplest thing you can do is to hook up and pull the rig onto scrap lumber. It will tell you 2 things when you reach level. You will be able to measure the rail clearance and you will be able to measure the thickness of the lumber under the rigs tires. The pin and hitch adjustment will give you rail clearance. For example if it needs 2 more inches of rail clearance you have to drop the pin box which will raise the nose of the fw but you will then also add 2 inches to the thickness of the lumber or the fw will be low in back again. The first issue is rail clearance.
There are numerous things that can be done to get a little or a lot of rig lift. Oh wait, let me bum you out a little more. Depending on how much you lift you may have entry step and rear stabilizer issues but remember we can help you with that too. :)
