I'd think that frame twisting is more likely than bending, given most trailer frame designs. The open C channel or angle iron longitudinal rails don't have much torsional strength.

A trailer shouldn't bend when you jack it by the bumper, but why take the chance? Also, many of our trailers are 10-40 years old. So they're corroded and fatigued, to the point where they aren't as strong as a new one. Better safe than broken.

The above may be a reference to one of these posts:

rear stabilizing jacks - post #14

If anyone is referring to these posts, please note that:
  1. in this case I had the wheels entirely off the ground, which is very different from just relieving some of the suspension load
  2. the trailer is indeed a Boler - a 17-foot B1700 - not the same as the original subject of this thread
  3. I did have the supporting jacks right back at the bumper, although under the frame, not the bumper itself
  4. the bend in the frame was so slight that it was not visually obvious (and I was working under the trailer); I have no concern with my trailer's structure in this situation
  5. I did not lift the trailer with stabilizing jacks - I lowered the tongue, placed jacks under the back, then raised the front... so the jacks under the back were not moved while supporting load (a technique which can be used with any stabilizer jack).

The full text of the second post (linked above) also has substantial additional information, which I think is relevant and of some value, but of course I'm biased.


If either of these are the post to which Carol was referring: good memory - these posts are from 6 and 5-1/2 years ago.

Information is good. Lack of information is not so good, but misinformation is much worse. Check facts, and apply common sense liberally.
