Blocking up a airstream.

[CraigCam]

Is there a safe way to jack up my 1970 overlander
and block it up in order to give me room to do some repairs underneath? There isn't much working room and I'm rather caustrophobic.

you can drive it up onto blocks that are graduated up. This makes the rear trailer wheels lift off the ground while the front is on the blocks. Add a jack stand or two for safety.
There are markings under the trailer where the jacks go. This is the same method for taking off a wheel.
Also use the search tool here to find other info on this topic & you will likely see photos of jacking methods.
Be smart don't work under there with no one around.

Jack it up and put as many layers of 2x10 lumber under the tires as needed to get the height you want. Do as much as you can with the trailer supported on wheels and tongue jack.
I probably wouldn't go higher than 6 2x10s to keep it stable. That will give you 9 more inches.

Thanks for the info and advice. I really appreciate it.

I simply jack on side at a time with a floor jack and place a jack stand with wood block under the frame rail just aft of the axle. Do the other side the same way. Then I alternate to get it as high as needed within the limits of the jack stand. Blocks are placed under the tongue jack to be able to level the trailer as needed.
