[VAC] Hot Water Heater Replacement

[thisisJohn]

Hello all,

I have a 1960 Tradewind which has a 120 volt AC water heater.  Since I do
not spend a lot of time where there are hookups I have thought about
replacing the AC heater with a propane heater.

The existing heater is under the double bed just inboard of the wheel well.
 My question is, what kind of job is it to provide for combustion exhaust
when the heater is blocked from the edge of the coach by the wheel?

Thanks...
