Our 16 foot Scamp is a 1990 and on a long road trip the front triangular
frame just in front of the fiberglass fatigued and started to separate.
I wouldn't have noticed except from a side view it was suddenly, visually sagging in front. We were half way to our gulf coast destination in farm country. We were able to
find a welder who came out and put in a piece of iron and welded it back together as best he could. A temp. job to be sure, but got us back on the road.
I can only imagine the catastrophe had it totally separated and dropped in high speed traffic!
The weld was so hot that it did almost ignite the white fiberglass exterior. Wet rags stopped that.
WE had a major weld job done after we returned . Lots of stress to both sides
after 15 years plus of bouncing a 3000# around on the roads and highways. Always inspect your undersides pre tripping!
