Let me start off by saying thanks to everyone on the .org for helping me out. With the posts on here plus a few tools and common sense, I have been able to do [nearly] everything myself on this truck saving me tons of money! This place has helped me out a lot especially trying to get an engineering degree while putting the necessary love and care into my 7.3
My reason for the post is a question about how my truck sits. Since it is a 2wd, it sat pretty low for my liking when I first got it. I had a leveling kit installed (by someone else which was a waste of money) and I believe it is a set of 2.5" blocks under my front coil springs and new longer shocks. This summer I needed to pull a 37ft fifth wheel to Shreveport for work so I bought a set of 2.5" add-a-leafs and put them on. The truck sat great and pulled like a champ during the heat of the summer! At the end of this summer I believe my michelins will be getting to the time of needing to be replaced so I am most likely going to go with some BFG all terrains. Id like to get at least 33's but possibly 35's if I can.
Before I start with my options I'll admit that my experience does not go much further than working on the engine of this truck so..
1. I'd like to learn and save money by doing it myself
2. Be nice if one of my ideas will not work because that's why I am asking you guys!
So first If I leave it as is, what size tires do you think I can fit under it?
Second, Would I be able to put a coil spring level on top of my blocks in the front? I'm thinking about 1.5" that way it doesn't make the a** end sit down and the front end up when I pull a boat or hay trailer, but still be able to fit bigger tires. I know I would need to get shims for the camber (is that right?) if I did this. Would I also need longer shocks?
I really want to do this if I can because I cannot justify lifting a 2wd truck for the amount it would cost all for looks alone. My truck will hardly ever see mud because I have been stuck in these things multiple times when they are 4x4...lets just say these diesel is way to heavy for mudding
(for me) and I want my truck to last me 10 more years

...
Is there another option for what I want not mentioned above?
P.S. I put about 15-20k a year on this truck. My grandpa sold it to me in august of 2011 with 44k on it!
Here's a reference picture. Let me know what y'all think!
