I have a 3.5 TONE trolley jack that I purchased from the local Northern Tool about a year ago. I've used it for the applications you mentioned about one-half dozen times and it's a beast. Short cranks to raise it and very well built.
I don't need it on my truck as I can now crawl under for oil changes but I did jack it once since my level and it has no problem.
Please do NOT forget some quality jack stands too as a piece of mind and backup
The brand/model escapes me but I'll check later today and get back with you.
Truck was sold today [5/19]. I got an offer I couldn't turn down. I had no more need for a pickup so I cut it loose. About to purchase a '14 Jeep SRT8 this week.
The regular duty craftsman I have now is actually the second. After about a year (maybe used it 4-5 times) it stopped working. I had to fight with them to replace it but they eventually did. I wouldn't expect a jack like that to fail with such little use...crazy.
The more I read reviews on even the heavy duty Craftsman they seem to get rated very low. I know more people have a tendency to write in when they have a bad experience rather than something good to say but a lot of similar reviews about them failing has me concerned.
And I thought this would be a simple purchase...
