I have seen a nice rack made under a trailer to house one of the 35 gallon totes. Tote just slid in the rack and was very secure. Wish I had a picture of it. We have a tote, but don't carry it anymore. With Jayco's high ground clearance, I think an undermount would be what I'd do, provided it's done right and secures the tank well. I've never heard one called a honey wagon and we've been doing this a long time. Guess I learned something. I just call it a tote tank or whatever comes to mind at the moment.
