2' over the full length of the 5er or 2' from wheels to pin? Also, wheels on the slope or wheels on the flat?
If it is 2' from wheels to pin then that is quite a slope & you are not going to get it level after removal from TV. If wheels are on the slope you had better chock them real good & make sure the weight is on the chocks before begining to remove the TV. Chock all wheels fwd. Nothing has ever defied gravity so no reason to chock them aft.
Have not seen any 5er legs with 2' of travel so leveling is going to be impossible without some creative use of bottle jacks & wood on the frame.
