Peanut came with an electric tongue jack...it did the job very well. HOWEVER, with it on, we could not open the tailgate/rear hatch on our Dodge Grand Caravan. The PO towed with the exact same model, and he said he couldn't open his rear hatch either, but he "didn't mind." Well, I minded, and Paul minded once I pointed out that he ought to.
We replaced it with a crank-down, fold-away tongue jack, and soon realized the tongue jacks usually come with wheels for a reason. So we replaced the replacement, and now it's fine.
Just be aware some tongue jacks are bigger/taller than others and pay attention to what you're towing it with. Not being able to access the rear of your vehicle might be an issue.
