Quickjacks - anyone used them?

[Heatmizer]

So as it says, has anyone used these? Don't have a huge space so a lift was out of the question, bought these on sale from costco. Problem is that the C10 frame has more elevation changes than most mountain ranges, so struggling to get these to lift the truck.

Have stacked the blocks a few different ways - safely and following Quickjack info - but the front end lifts way before I can get close to the rear of the frame - stll 5-6" away. The front blocks end up flexing rearward so I've stopped for now.

It's a shortbox if that matters with dual tanks. No I don't have the extension kit for trucks yet, could be my problem. Hoping to pick those up in a few weeks.

The truck itself sits pretty flat, it's not jacked up in the rear or anything.

Any help appreciated.

not completely related but I seen something new to me a few days back:

I was just in a tire shop, and a rusty suburban came in, and they jacked it with 4 floor jacks and not the regular industrial quick jacks. (5,500 lb things they seem to lift with the tire quick jacks and a floor jack just to take some weight off the quick jacks....which might be getting old, leak or sag).

but in this case last week as a new procedure:
one regular HD floor jack on each corner of the frame.

what quick jack make/ model did you buy from costco?

what kit pieces do you have ?

They're called Quickjacks, made by Ben pack. Got the 7000TL version. Seem to have a lot of decent reviews and they were on sale. Hopefully I can make them work.
