I went with the Equalizer. The rest of the story, if you're interested...
Besides my 23x2, I have a Dutchmen 28A that my daughter is using. It has the Bigfoot system, which has been working fine for three years now. The reason I was asking about Equalizer was that when I had the Bigfoot installed at a dealer there were discrepancies in the manufacturer documentation regarding the placement of brackets. Because of the rework this caused, even after splitting the difference with the dealer, cost me 50% more than expected. When I contacted the manufacturer afterward about this they were unresponsive. Hmmm....
So, after reading the Rolls Royce vs Bentley comments, I figured I wouldn't go wrong with either system if I could get a fixed-price install. For this, I went to the Equalizer plant and had them install the system figuring they do this every day. As we all know too well, Murphy never sleeps. I discovered when I got home that the jacks were installed at the wrong height (bolts, not welds). We were going near enough to Elkhart on an upcoming trip to arrange another visit. This time the jacks were adjusted as they should have been. Equalizer folks agreed that their techs screwed up the original height settings. And, still a warranty fix of course.
Bottom line: Second trip would have been a serious PITA had we not been traveling nearby anyway, but the newest Equalizer system is working properly. It has Bluetooth so I can operate it from outside while watching the jacks.
I'm aware others on this list have discussed why these systems are not necessary (no argument about the expense!), but we are frequently on soft ground in close-quarters so driving on leveling blocks is a problem (TW is physically unable to be the spotter). Also, being able to adjust the level when if the soil settles is very helpful.
Do I have a Rolls Royce or a Bentley?
