Well, since our closest Costco is 80 miles...ea way...not messing with that. Thinking I'll check into the HF and the other one.....IIRC, Tractor Supply??? Those are both closeby, on our way most anywhere we're going and they both stand behind their stuff. AND....fits into what I was thinking this is really worth in terms of how it'll get used. We have never, in 8 years camped without hookups and I don't see it happening. If we have a problem at home, the big one can be pulled out and put in use. PS....will invest in a couple of good spark plugs for stocking stuffers.
