Have a 08 King Cab, LWB, 4x4. Using it for farm work, still have a heavy 2000, 3/4 ton GMC for the heavy work, but side by side that Titan dwarfs that GMC and since then I have decided that Titan ought to be able to do about what that GMC does. First got the truck because it was cheap, used with low mileage, even though I was lookin for another 3/4 ton. But I have hauled my pull behind stock trailer loaded with a GVWR of #7000 and I can see I need to beef up the hind end a little, of course, I was not using a WD hitch, would like to not have to mess with that. I went to a local frame shop and was going to order the Air lift bags but he said they only have a 2000 lb. capacity bag and it was almost $350.00 just for the bags alone. How about adding a leaf on each side? If so, where do you get the extra leaf? Can I get by without using a WD hitch. Also, anybody putting 50 bales of hay in a titan. I did, figured it at about 2000 lbs. Handled it alot better then my older F-150 and Dodge 1500, but it was still definitely a 1/2 ton. Wonder if beefy up the suspension I could do that on a regular basis with out hurting the axle and bearings.
