Ha Ha, that's classic.. typical scenario in my axle search too. Hopefully your current setup will keep you on(or off the road) for a while.
Re the crossover. Man, my truck drives so sweet with my setup. I can take my hands off the wheel on the freeway at 60 and it tracks straight, over bumps and everything. It's never driven so good. My advise, if you ain't hard core wheeling and your vehicle tracks good... don't jack it up. I feel like I got lucky on my current setup. Maybe not luck, but my expectations have been surpassed by the way this truck handles! And it could probably even use a king pin knuckle spring and bushing replacement. But I don't think I could get it to handle any better, maybe HD springs up front. I used to gripe about the 4" Skyjacker soft rides up front being too mushy. Now that is not a pet peeve anymore because it just hugs the road.
Anyhow, you know the old saying... if it works don't fix it.
As always my 2cents... worth the price paid!
