Most IFS lifts dont increase the amount of travel you have unless the kit comes with longer A-arms (which will push your wheel mounting surface out). Most lift kits only drop the IFS down. You might need a longer shock since the lower-shock mounting point is now X-inches lower, but the amount of shock travel is the same.
Im not familiar with the Camburg kit but the design might push the shock out more -- which would require a shock with greater displacement/travel.
If a desert truck is you're goal, then I would save up some cash and build my own A-arms. I hope you have a 2wd cauz that would allow you to push the A-arms closer together and have plenty of travel -- same concept as the trophy trucks which run arms that are practically pivoting next to each other. Of course you can only push them in just a little bit cauz of the engine block but every little tid-bit counts towards a plush suspension.
No reservoirs though
