Where's the jack??!!

Aren't those "goofy" screws Robertson #2 screw heads? (ie: square ones)?

Those are the norm in Canada (and were invented by a Canadian, likely why they're not widely used in the US). Here's a bit of info on them for you! =)

With regards to the rest, I have a bottle jack I carry as well. I made sure to buy one that goes up plenty high enough with a little help from some of the 2x6"'s I use to level the trailer when parked.

Corner Jacks are rated to 5000lb each. I can't imagine lifting that much with them though.

I have lifted the curb side of my TM 2720 by using just the two corner jacks.

I tried using the jack from the truck, but it did not go up high enough. I suppose I could have put my Lego blocks under it.

I was not able to lift it using my cordless drill. I had to use the hand crank. It was not too difficult. In fact, I think I can spin the hand crank faster than I could pump a bottle jack, so I think the hand crank is faster than any hydraulic bottle jack that I have ever owned.

My TM only weighs about 4,100 pounds loaded.
