If you need to jack up a fifth wheel trailer, there are a few things that you will want to keep in mind. Here is a quick guide that can help you through the process:
Use the Proper Tools
Be sure that the tools are appropriate for trailer that you are working on. Many times there are weight limits for the loads that the jacks can handle. So you will want to check the manual on the trailer or estimate the weight so that you don't have any problems. Be sure that the jack is in working order before you begin the process so that no one is in danger.
Park on Solid Ground
If at all possible, you will want to try to park on solid and level ground. This will help to ensure that the jack is lifted up completely and that it doesn't fall down while you are working.
Check the Manual
Check the manual to see where you should place the jack. Typically you will want to be sure that you are placing the jack under the trailer completely so that it doesn't slip out while you are working. Many times your manual will have a special section for jacking.
