How does a regular bottle jack fit under an axle? I ended up buying a double ram Torin jack that is about 6" tall collapsed (14" max extended) so it would fit under the U-bolts along with a piece of 2x4. Some axles are under the springs (like ours) and some are over which are safer to put a jack under. One of these days I'm going to make a custom saddle from steel pipe for the jack so it fits perfectly under the U-bolts and can't slip. This jack makes it easy for inspecting/serving brakes & wheel bearings at home.
If we didn't have a jack and had a flat on a trip, I'd be making a ramp from our lego blocks and putting one on each side so the trailer doesn't have to tip over.
