@Lane Anderson the 3500# unit is 62" overall and the 5000# unit is 70" overall. Here are all the dimensions: https://www.quickjack.com/quic...measuring-guide.html
@IaM-Ray you say "Look at the space between the wheels that is the critical measurement". Using their method of measurement I got a 60" tire spread measurement and they say I need 62" for the 3500# unit. I am not sure how accurate my measurement was. Is this only an issue if you want to slide the frames under from outside the car? Could the longer 5000# unit be used if it was under the car before being slid into position?
