As a dealer tech I do alot of heavy engine repair on trucks. The newer design trucks no longer have a bumper to kneel on and the engines sit very low in the bay , as a result I have hurt my back several times trying to lift heads out and even breaking the bolts loose due to the poor positioning of ur back during the repair , I spent over 700 on another topside creeper and it helped but still had back issues , I saw this advertised on tik tok and ordered immediately , and thought this better be awesome for the price , I have never been more satisfied with a tool , worth every penny and would highly recommend to any tech working on trucks , this is a game changer!
