One day my grandfather was wheelin in his stock Jeep Wagoner with his buddy following behind him in his well modified Ford pick up, it had a lift kit, tall tires, a big engine, ect. My Grandfather went through a prety deep mudd hole with no problem then his friend followed taking the same line my grandfather did and for some reason he managed to get that truck stuck. Then in ,need of a little help, he slamed on the horn because my grandfather wasn't paying any attention to what was happening behide him. Once my grandfather realilized what happened turned his Jeep around drove through the hole to the side of his buddys truck turned back around and pushed his fiends truck out with his Jeep. Needless to say my grandfathers friend was a little embaresed.  

Those old Wagoneers were tanks in there own right and well built. There were designed as a 4x4 from day one not as a 2wd that is converted to support 4x4 too. I have a  stock 79 J20 and under it it is clean with nothing hanging below frame rails (you could drag it on rocks and not hurt vitals) because is was born as a 4x4. My grandfather had a 63 Wagnoneer that he pre ordered (first year built) and he towed and pushed snow with it for over 20 years and never had any problems with it. My 79 pushed snow for over 15 years and towed many more and it never broke down on job either. On winter back in 90's we had a blizzard and I had about a ton of weight in back of J20 and a set of full tire chains on each wheel and was plowing out badly drifted gravel lanes with for tires spinning at times and snow coming over hood at times too and she did not fail. The strain on that truck, drive train and frame had to be extreme at times but it never even wimpered. If I tried that with a modern 4x4 I would tear it apart.
