I had the same issue with our 82 Scamp
that was already very experienced by the time we acquired it. I even spent the greater part of a sunny Sunday afternoon at the picnic table carefully sanding what was left of the original paint to bright steel. After thoroughly degreasing it with lacquer thinner I sprayed several coats of high heat paint.
It ddn't hold up to the amount of cooking the 'love-of-my-life' likes to engage herself in, even when traveling. It was soon no better than before. I tried to purchase a new stove-top but the company had long discontinued this model and had no parts left to sell.
Good fortune came my way when I found a slightly used "Force 10 Gourmet Galley Range at a yacht supply on consignment for about 1/2 of new price. It was the same size as most camper ranges and fit in with little modification of the cabinetry, needed because it had an oven where the original was just a cook top.
Life on the road became so much better as that shiny stainless steel range brought joy to her heart and a love for that little Scamp
that fit our traveling needs so well! That and a new Max Air vent/fan and she was right in her element sauteing in her small wok.
After that she insisted that I also get something special for the Scamp
. I chose a small Dickenson propane
fireplace. What a wonderful way to end a day of traveling with a small gourmet dinner for two, enjoyed in the flickering ambiance of that little fireplace in our little fiberglass RV.
It's the good life!!!
