Rookie Question - Landing Gear with single motor - Movement

Single motor drives BOTH sides equally......

So if both legs are not touching ground after dropping inner tubes then one leg assembly will start lifting trailer before other takes some load. This can cause twisting of frame and failure of landing gear leg (shear pins/drive gear/jam nut)

Best to have both touching ground prior to extending (raising 5vr)
Shovel to dig out highside, small thin blocks for shims OR adjustable foot pads (Winfield RV Products)

It's very unlikely there is any kind of clutch. And using just one leg to raise the front will most likely put a lot of strain on the motor, the one leg, and the frame, all of which can't be good IMO.

I have a Fuzion toyhauler with a single motor front landing gear which sounds very similar to yours. If I can't get it level with adjusting the legs with the pins, then I either use a small block under the leg, which I rarely have, or I take out the bolt that secures the telescoping connecting tube for the two legs. Then I raise the opposite leg by turning the tube until the legs will be level. Then I line the holes up and put the bolt back.

It's not a big deal and insures that both legs at least start out level.

I too carry 1/4 and 1/2 inch squares of plywood to fine tune the landing gear length.

If your off road I suggest you always have a shovel- A shovel of dirt added/removed is a great way to adjust and you don't have to carry anything extra.

I carry a small assortment of 1", 1/2" and 1/4" boards to make up the difference, that is also a device that can be added to one leg to screw down to make up the difference.
