You would think that ABS being successfully used in a dwelling (camper) that is undergoing constant seismic activity (towing) would make it suitable for a fixed structure. My house was plumbed with ABS drain pipe when it was converted to sewer before my purchase. So far so good after 25+ years.
I did need some ABS when I replaced the black tank in the camper last year. The only place I've seen it locally is the RV dealer. Nothing in the big box stores.
