Spare tire should not be hard, I ordered a new set of tires
on line from
Trailer Parts Superstore
used one of the old ones for my spare, if you need a bracket, they also sell them. Propane
tank you can carry in your tow and just hook up when the other runs empty, that way you can always get it filled at hardware or gas stations with the Rhino. If you want to mount then it gets a little complicated with an automatic switchover. I have a stereo, new in the box you can have, you need to pay shipping. It's an under cabinet style that someone gave me, brand new. Not sure what the wattage is. If you want I can get a picture tomorrow.
