The manual states that my trailer is not intended for permanent housing or full time use but for recreational use. That is pretty vague language. How many days of use per year is considered recreational? As for the frame and suspension, how many miles a year are considered normal use? What does Heartland consider the normal life of my camper to be? I understand there is maintenance that needs to be done but rather than the manual saying to inspect the suspension every 6 months I would like to know how many miles I can go between inspections.
