jacking a trailer

[rog4kneer]

Had a 31 foot jayco designer travel trailer moved from one campground to another. My trailer needs to be jacked in order to level side to side, and also to put a piece of wood beneath all wheels. What is the best location to use when jacking this trailer. I plan on using 12 ton jacks, what is the best location for jack placement. Any info will be greatly appreciated. Moving the trailer is not an option.

It is best to place the jack under the frame of the TT just fore or aft of the axles (not under the axle). If you are at a seasonal site, you should be able to find someone with a truck that can help move it forwards to lay down your wheel blocking.
