I had quite a few leaks with mine. But now I love the camper after attacking all of them. The most difficult one to locate was the leak getting into the campers belly from the outside propane compartment door hinge. I would have never known it if I had not seen the water running inside except I had cut an access hole to get under the bathroom sink. As soon as it rained water would run from somewhere forward, under that sink and toward the rear. A good NL owner should store his camper so it's got a slight angle to the rear sewer outlet as any leak will advertise itself there that needs attention. The door hinge was unsealed and would have never been able to find it till I squirt water at the camper to locate it. It was very frustrating otherwise.
I was around boatyards with larger yachts for about ten years. It taught me the correct way of sealing leaks to a fiberglass body. I'm very fortunate to have this experience and bring my NL camper up to that standard as it had many leaks from the first day I brought it home brand new.
The other frustration was the basement structure failing/ falling under the campers own weight. I fixed that also, knowing that I'm a better craftsman than the builder, I declined the manufacturer's offer to repair it, even though the offer was well beyond warrantee and very commendable on his part to make such an offer...
