Having used many combinations of jacks of any and all descriptions there's simply no better option than the Hummer-type heavy duty for raising a van that approaches 7,500 # and more. Add in larger tires and 4X4 drive trains and you're dealing with lifting situations most every other "portable" jack was never ever intended to encounter. For what we use them for there's no compromise made relating to being safe during a tire change.
The Agile adapter is a highly recommended additional part that adds another safety factor---in all honesty the Hummer jack's lifting pad isn't well suited to a van so I'd say this is a huge must have when going this route.
Having used one to swap a slow leaking tire I was surprised how easily it was to raise the rear left corner of my van, stability was great for this task.
As a distant second-best jack the Powerbuilt Unijack would be something to consider however it doesn't lower enough to fit under an axle that has a flat tire. While I have one and would use it on a hard flat surface the Hummer-type is better suited for roadside on off-road use. Unijack link: https://www.powerbuilt.com/products/...ckstand-in-one
These can be found for $50-60 with a little shopping around.
The Unijacks also require a bit more floor space when stowing--the Hummer-type are remarkably compact and could easily fit under an E-Series front seat in a lot of instances.
So that's just my $0.02 worth---FWIW.
