Benita, I've been giving a very hard, long look at that type of stove. It is way more expensive than the typical RV stove, but I think it would be worth it. I believe they are made for boats.
Seeing it put to use as I imagined makes me really believe it'd be a good idea.
Suz -- We are up in western Washington. Puget Sound is all around us as are millions of boats. I found a used Force 10 range for about half price of new at a used boat equipment place in Seattle and installed in in our 16ft Scamp
. For sure it is 'way better' than anything made for campers.
You show your area as North Texas, and I have driven enough miles in Texas to know it can be a long ways between places, but I would think any of the towns from Galvaston to Pt. Isabel would have a lot of marine stuff in the consignment shops.
Perhaps you could just hook up and head out to the coast for a few days of a mini-vacation and improve the time by lurking around the warves and docks. Never know what kind of treasure you might hook into.
