Help me decide on a floor jack

If my 1978 Sears 1 1/2 ton floor jack dies before I do, I'll probably try and rebuild it. I've considered buying the HF 3 ton aluminum in the link above, just to carry with me on road trips with the car trailer. Old faithful I talked about above weighs 600 lbs.....or feels like it to my 66 year old joints. Seems like it's a lot further to the tailgate from the ground than it was when I got that jack at 21! :BangHead:
