Front Jacks - Do Holes Have To Match?

[Dr Dolittle]

At the end of our delivery walk through, we talked about hitching and unhitching. BTW, this is our first fifth wheel. Tech said that when manually lowering the front landing gear, before using the leveling system to get the trailer weight off of the truck, it's important to count the exposed holes and make sure each leg matches.

Is this correct? If so, why is this important? I use the yellow Lego blocks under the legs so the leveling system doesn't come anywhere close to full extension.

I say not!, I never worry about the number of holes each front jack is extended. To compensate for sites being unlevel, I lower the front jacks until one is almost touching the blocks I set on the ground, adjust a jack down a hole, one or the other until they both are even almost touching the blocks, then take the wait off the truck.

I’ve done the same on trailers with an electric leveling system. Never an issue.

Thanks, it didn't make a whole lot of sense to me when he said it but I didn't question him at the time so I figured I'd better ask here.

I Never worry about that. I use my hand to measure the distance from whatever blocks I have placed down, and adjust the legs so they are the same distance from the blocks.

Maybe that's what the tech was actually saying, too. On level ground, his technique should have the same results as yours.

We would lower the jacks about 1/2 way, drop the extensions to the blocks, then raise the extensions to the 1st hole available. We never counted the holes.

Same process that I've always used (as demonstrated by the dealer.)

Maybe the tech has Symmetry OCD and he was trying to spread it to you. Looks like you caught it in time and came here for advice instead.
But seriously, like other have said it's not important. Also if a left or right jack is higher than the other, you can lower one leg individually by pressing Left or Right on the panel to align both feet so they land evenly. Then unhook and follow up with Autolevel.

The term 'tech' used to mean a specialist in a particular field. Now it's a name they give a person on their first day of work. We need a new term for a knowledgeable, experienced, capable person in their field.

That would be the guy that quit last week and was replaced by the front desk person.

In auto mechanics that would be a master mechanic.
