Everyone's experience is different, ours is, and we LOVE our 2nd motor for the front legs.
I have been told that many of the larger units have 2 motors, I thought I heard that some are even coming from the manufacturers that way, but, you know, should not trust the ole gal's memory, it tends to leak.
John's concern about getting the unit in a twist is not to be taken lightly, but, I trust CountryGuy's diligent care during this part of Tana set up. Note: That both motors can be run at the same time and he tells me that he checked to be sure that they were indeed running in complete sync. In other words, they both raise the same amount, so when both switches are engaged at the same time, both sides of the trailer go up equally, the legs extend equally.
Our fix of adding a 2nd motor was not cheap, but, it has solved the problem of the click click click, and now we don't have to worry that Tana and Big Butt will mate for life, errrr, we know we can get Tana unhooked from Big Butt.
