Removing 5th wheel Hitch from pick up bed

Thanks all- a lot of good stuff here to chew on. Am going to give it a shot today. Because of all the vehicle shuffling I eventually have to do in this drill, I think initially I am going to opt on the first try to pull the large pin on the upper part of the hitch and lift it off rather than leaving on the king pin (might do that on a later project). Then after a swig of Geritol I am going to pull the 4 lower rail pins and try to impress Momma and lift it off(while she rolls on the floor laughing at me).

If this all fails I will await the arrival of the block and tackle I ordered from Amazon- which should easily attach to the garage ceiling beam and joist anchors I have in place.

If you all hear a bunch of wailing, screaming and hollerin you will know I messed up.

Thanks all for the good input and helping build my confidence in completing this drill!
