Sorry I can't answer your question as the jack was bought as a gift for a friend.

Sort of...you can move the frame adapters horizontally along the length of the jack as needed. You can also unscrew the adapter up to approx. 2 inches before losing the threads--which helps adjust to fit your frame.The adapters are the least useful part of the jack. I use them less to catch the frame than to balance the frame on the jack itself.

It requires muscle and a 7/8" wrench to raise the jack. I wouldn't suggest an air wrench.

I'm not an engineer, so I can't directly answer that question. My travel trailer is between 3000 and 3500 # (depending on the load) and the jack lifts and supports the wheel. If I need to lift it several inches it can take a while to crank it by hand, but it does a fine job getting the trailer level. I have recently tried using an impact drill to raise the jack (because this type of drill does not twist your wrist) but there were some problems with that approach. The jack-screw started to show signs of metel shavings which might mean I am near the limit of the jack's weight load. That said - I would buy another one of these if this one breaks. If you get one you might also want to buy a large pizza-delivery bag to store it in. Works perfect.

No, there isn't. But a longer neck would be dangerous because the higher the neck, the less stable the jack base. You can increase its lift by putting the jack wheels on a board or a plank on the ground; for example, a 2" by 6" by 30" long board would give you almost 2 more inches in height as well as maintaining a stable base. This is not a heavy duty jack to begin with; it's small with a narrow and small footprint. More weight and a higher lift reveal its stability problems very quickly. I hope this helps.

There is no warranty period listed in the manual for this jack. I have heard it is a year warranty but I cannot confirm with the included documentation.

It's only about 5 inches long. It is designed more to serve as a thinner jack connector than an extender.

Sure - it'll work great, you just have to apply some pressure to the jack. Let us all know how it works out for you.

Probably about 30 - 45 min depending on you level of experience. Not difficult but important that you use enough glue and tighten well. I had one screw in particular that gave me trouble.

I never tried to extend it much beyond the 4 feet. But please for your own sake, do not buy this waste of money! It... Does... Not....work!

You must have a low clearance garage. The J bars fold down and only add a few inches of height in the collapsed position. But if you don't have a few extra inches, they remove with two hand-tighten nuts each. So it would take 15 minutes to take them on & off, but not something you'd want to to every weekend. We leave ours on all the time, just flipped down. Except for one trip to the lumber store when we loaded them up with a bunch of 2 x 4s. :-)

A simple hacksaw, 1/16 drill and small Philips can do it about fifteen minutes. I shortened mine to about 44". Remove small Philips screw which holds plastic end cap located opposite the lockable fastener. Push off molded plastic end cap measure to new length and saw squarely. Drill new hole for endcap screw then reassemble.

About 5 minutes when unloading two bikes. It requires an hex (allen) wrench which is supplied with the carrier but I bought an adapter for my socket wrench so I could install/uninstall more quickly.

On solid piece of memory foam 4" thick. It is vacuum packed so has to be allowed to expand over 24 hours.

Not long. May be 2 hours. I don't move it around and it is not an issue for me.
