New 5th Wheel. Anything I should get before picking it up?

Take a look at locations on your electric fresh water and sewer hookups and compare to your previous RV. You may need a little more electric cord hose or sewer hose based on the new locations.

I actually use less fresh water and sewer hose and a little more electric with my new 5th wheel over my previous one.

It's also a very good time to take a look at everything you are taking out of the old trailer and ask do I really need this or not. It's surprising how much stuff you can accumulate over the years!
