I visited harbor freight (HF) today. The 1.5 ton aluminum jack that DCi (post #28 ) linked to was really nice, especially the weight (30-40 pounds) and length, but the deal breaker (no go) was it could only lift to 14 and 3/8 inches. This is an inch above my scissor jack's maximum height.
The HF 3 ton heavy duty jack, is indeed very heavy, and would be unwise to bring on a road trip.
If one knows of any other aluminum jack with 1.5 to 3 ton capacity with around 30 pounds in weight, and less than $150 shipped, it would be appreciated. High rated user reviews, is something I keep in mind. Although this seems very unlikely.
By the way, is the following meant to mean anything, "Bend this tab after inserting ratchet bar". Completely metallic. The only mechanism i notice, is to push the the handle slight sideways from left to right, which doesn't seem to have much effect to the stability of the ratchet masts.

Trust me, I "RTFM". The orange phalic object was referred to as "ratchet mast" in the manual not "ratchet bar".

Only way the ratchet mast could sink in is, if the the handle is lifted (which will be near impossible due to weight being weighed down on the mast, or if the jagged hooks all snapped at once. These jack stands is, have minimum height of 9.5 inches, when the mast is full submerged into the base.

By the way the Highlander is a "crossover suv" weighing under 3800lbs (1.9 tons).
Thanks to those who have provided constructive posts.
Edit 2: These seem good, but a bit too pricey
. Cheaper than anything on Amazon though!

Ford Excursion Turbo diesel is 7725lbs. To just lift the front, I guess the 2 ton would do! I'm indeed leaning toward the HF $160 floor jack.
