Thanks for the question...while you are in bed, simply stand up in the dressing room area and lift the foot of the bed (it has a support rod to hold it up while you look around (I added a 3 bulb LED for "nught" searches)
An ARB or Engel will not fir in the storage area, but if you look at the video that Jose posted you will see a tongue rack that we added (supposed to go into a truck's reciever hitch, but slides right over the tongue of the trailer) We carried 10 gals H2O, 10 gals gas and a bunch of firewood down to Baja and back..fridge shouldn't be an issue
...as they say when you're building a hot rod...some modifiaction may be required
If the "Steinborn" pics dont show everything you need...call or email dizzyspots at aol dot com and I'll take more
cheers
Mike
