I'll sell you mine for $1,000,000
I did not recive a owners manual with my Fun Finder xtra 200. My dealer had gone out of business so I call Cruser RV and they sent me one at no charge. Give them a call, they are real nice people. 260.562.3500 or Toll Free @ 866.277.5630
I'd start by finding someone with an RV in your neighborhood, and ask them for a walk thru. For the most part most RV's have very similar equipment. Barring that I would google each appliance for a manual. But definitely spend a weekend "camping" in the driveway to make sure you understand how everything works and to make sure you have everything you require. One thing that is always sitting on the dinette table in the trailer (aside from my 9month old's pac'n play) is a pen and pad of paper to write down anything we think we need or forgot.
The jacks are lowered with a crank, that could be stored anywhere.
You'll know it when you see it as it looks like one of the old school cranks on the front of a car that has a socket-type attachment on the end.
Either way enjoy your trailer.
