Why would you need to worry about sync'ing them? Put in 2 switches to control them separately.

Except if one is slowing down, then they would not be running at the same speed.. Sure you could run them separate to get them back even, but no guarantees they are going to run the same speed pushing both switches at the same time .

Grease. Mine started blowing fuses. I put the truck under it so I could pull the legs out. Somewhere on this site I found a home made contraption that works great. Basically it's a piece of rubber hose, mines clear probably 1 1/2 or close to it that you then add several adapters to to get it down to a grease zirk on the end. You feed the large hose up over your leg screws and apply grease to the zirk.
Used it once 2 years ago. Motor doesn't work hard at all anymore.

It is a very simple matter to hold the rocker switches on for both sides. Operate each till touching ground then both. Easy. Can't imagine not having a motor for each leg.

There ere no zirks on mine so the only way to lube is to remove the top cap and pour or spray from the top.

I've =seen= factory installed 2-motor/2-switch legs in operation and they =always= had to adjust one side as that motor just ran faster when both switches were pressed at the same time. (FWIW, old GF's father's FW.) The 4-pt system on my KZ, on a virtually level concrete pad always runs one more than the other. You simply can't sync the motors that closely without complex and expensive electronics involved.

Other thing about having 2 motors is that the legs jack about 2x faster, if not more, than a single motor setup. Old Komfort had the single motor and it was =slow=!

I think we are agreeing here [emoticon] Two motors ,two landing gears one is binding a bit or needs grease, although obviously they are both geared the same.

Case in point with the 2010, motor booked down to a stop, just didn't have the power to turn both. Pulled the drive side off,had a bad spot in the worm gear where it would not turn at all by hand. He ordered a new leg, although it ran , it was very slow. Pulled the opposite side off, and turned by hand ,it was pretty stiff, greased it up, and things ran well.

I guess my point is, I don't think the OP needs a double motor , he needs to just get those gears lubed up somehow.

Yes ,but we are missing the point here or are we [emoticon], if one is binding a bit ,then no they won't run the same speed, and will have to be adjusted independently , thats the nice thing, but then again you still have to watch ,and make sure you are not coming up crooked ,and putting more bind on the legs.

Keeping them lubed up, and not over extending them to the end, and messing up the worm gear, then regardless one or two motors, they will run okay.

Mine with one motor runs fine after messing up some gears, and having to replace one, then knowing what to do.

When I had my old fifth wheel with those telescoping legs, I greased the zerk and it only helped a bit... I sprayed the **** out of the inside of the legs with lubricant, I sprayed until it was running out of the bottom..... That freed up my binding issue..

I know for a fact , they don't run well with no grease, if you have put a bit of a bind on them ,and burred them worm gears, then two motors may help ,but it will struggle still .

I know my 2008 has just the one zerk, to grease just the top gears. IMO ,they are not the issue ,its that long worm gear thats the problem . They need grease, or if they have been a bit over extended, they are toast , grease will hep some ,but they are burred .

Actually the OP didn't say anything about his motor binding up, he just commented that it runs really slow and labors. And they do run very slow even when new. My Fuzion ran so slow that you basically had to chalk the legs to see if they were moving. But I do agree that keeping them lubed is a very good idea.

"I've =seen= factory installed 2-motor/2-switch legs in operation and they =always= had to adjust one side as that motor just ran faster when both switches were pressed at the same time.

A fair amount of misinformation here, I have the Bulldog unit with two motors, and two switches. The motors run the same speed, no fancy electronics that I can tell. But they go up and down with no adjustment needed unless the ground is unlevel.

As for double motors running 2X as fast as a single motor, that's not necessarily true. They may run a lot faster, but they also may only run a little faster. The Bulldog system has two settings: High Speed, and High Torque. One is pretty fast, and the other isn't a whole lot faster, but still some faster.
