Jim, my trailer is the same model as AzMichael and my trailer does not have the outriggers you are talking about either. My trailer has the rubber bumpers on the front and rear end of the trailer and I have had to reglue one of them before in the past.
The trailer does seem to go down to far as mentioned by Michaels post and usually I have to raise the trailer slightly to get it high enough to where I can open the storage door where my battery and pump are located by the door. I take my battery out when not in use and keep on a battery tender in the garage, so it makes it a little difficult to get the battery back in the storage when going to pickup the trailer. I have to basically lift the trailer slightly by lifting with my hands while my wife opens the storage door for access. All I can say is that its a good thing I keep in shape, it is a little heavy!
I have thought about maybe putting a piece of 2x4 under the top somewhere near the middle section to keep it resting on it while in storage, but not sure if that would work or maybe do some type of damage?
