By nature the 7-blade connector has a scraping action each time the plug is inserted which is a cleaning action for the contacts. So with a cover, a 7-blade receptacle should last a long time. The plugs tend not to last as long, no cover.

The 6-pin round connectors are terrible. The spring action comes from the pins having a split in them with an outward pressure against the sleeve connectors. Over time the springiness of the pins fades and the poor contact pressure allows corrosion to build.

The ideal setup would be a 7-blade connector at the toad end but the receptacle is very bulky and not pleasant to look at when not i use.

Since we only need four wires, we set up the toad connector to be easily replaced every other year with flat-4 connectors.

Not long, really. Both receptacles went through 8,000 miles in three-and-a-half months last Winter. The ProPlug got sold with the coach in June. I still have the Hopkins receptacle on the toad and the cable, so there's a chance we'll put more miles on them both.

One thing I did NOT like about the Hopkins receptacle is how difficult it was to put the rear cover on. An extra quarter-inch in the cover depth would have helped.

Pictures are below. The toad receptacle picture is missing its fourth mounting bolt, as I took the picture before I finished the wiring.

I'm looking at the ez connector system http://ezconnector.com/ but before going to the trouble of wiring it in I thought I'd ask if anyone has any experience with it, or an alternative that works better than the normal crappy connectors sold by RV places.
I used it on a travel trailer a few years back. It works very well as the magnet that holds it on is VERY strong. Only problem I had is that I have arthritis in my hands and wrists and it could be hard to pull out. I used a large screwdriver as a pry bar and it made it pretty easy.

jrwitt - thanks for the report.

Given the crappy weather here at this time of year and the fact that the coach is stored about 40 minutes away, I've done what I can from the comfort of my home and for the lowest cost. I've re-wired the Blue Ox cable with two new Pollak ends.

I'll see how that works out and if I'm not completely happy I'll replace the coach end with a ProPlug, possibly in January when I'm down south and lying on the ground is not such a hardship!

Thanks for posting about this plug. I too am having problems with my 7 pin and definitely need something better. I'd really like to see it before I buy though. Perhaps someone in the Big Tent at Quartzsite will be selling them this year.

Well Pigman,
We've been the big "Q" several times and, I cannot remember any vendors selling or advertising any replacement or aftermarket 7-pin plugs other than Blue Ox in their booth, selling the original ones. But, that doesn't mean none were there, it just means I don't remember any. We'll more than likely be there too, especially since it's only about 1.5 hours from us.
