I have never heard of H L, but I can tell you they are no better and no worse than all the others. Many of them come out of the assembly fine, then there are a few that get really screwed up.
They are located in Elkhart Indiana just like most of the other manufacturers. To me this means they have a limited pool of workers to pick from hence the RV
s will have the same quality. Really the parts are all the same in all the RV's with the only difference being the outer shell. If you like the look of the trailer all you can do is go look it over with a very critical eye. Probably the best thing you can do is go to the dealer when it's raining and stand inside checking all the corners and under the windows for any sign of leakage.
