RVing attitude has changed immensely since the old days of solid trailers with tags like "entry level"....I have two pre '75 travel trailers in my driveway that are unscathed by the years seeing more gravel washboardy roads than pavement and held the snow and weather of central Idaho without a leak.
Security and Kit are there names, both out of buisness but they give up nothing to the Airstream in longevity.
All trailers will have issues regardless of the tag new rvers want to hang on them. I have a 5 year old keystone that I haven't put .10 cents in repairs and it also has seen more gravel and dirt roads than pavement but some would call it "entry level".... If that's the case, that's all I'll buy then.. Sticks and tin and years and years of use.
