What issue should I be aware of on used Northern Lites

I love my NL, but like all RV's they can have issues. Check all the standard issues that you normally would, look for soft spots around windows, doors and vents. Check the floor (in the basement if it has one) for soft spots or signs of water. Look in cupboards for signs of water. Also look along the side of the camper, especially around the start of the cab over for bulging and separation of the fiberglass.

Many things can be easily fixed or adjusted if the camper is in overall good shape.
