I ordered one and it 'should" be delivered on Thursday, of course it went on sale 3 days after I bought it. I have been thinking about mounting it on a Front Runner rack and may have, in my designers eye, come up with a mount that will work with flat bars. several solutions come to mind. I'll know soon.
I have sent request to Costco for price adjustment, hope it works. The difference of $40 is sugnificant to me.
Please post your solution to mounting to the Front Runner. Would be very curious to see your solution.
This thing looks pretty handy. We have used the Nemo Helio, which is nice, but the Waterport would be nice if hitch mounted. For those that have these, do you feel the hitch mount option is robust enough for driving on rough or washboarded roads with the unit full of water?
ETA: Watching the video clip on the Costco site, at :28 when the guy is pumping up the Waterport, it looks like it's moving around a lot. Doesn't look like the hitch mount is very solid in this example.
Not sure if this video link will work here, but I'll try.
I agree with @gunsandgearnetwork that the hitch is definitely beefy. It attaches to the water port solidly but there is some slop in the receiver itself. Maybe put a shim in it? But its not going to do much damage.
