Questions on slow moving slide

I've noticed this year my slide extending and retracting has gotten slower and seems like it could stop working at any time. I don't retract or extend the slide on battery power, only 30amp. Is there any maintenance I should do or just take it to RV repair guy to look at?

Have you lubricated the slide since you've owned it?

Have you lubed the slide out rails? Mine are a rack and pinion type and real easy to clean and lube. I do mine at least twice a year with ProtectAll Dry Slide Lube spray. I believe it is only like $15 from Amazon. That may help and save you money......that may be all the RV shop would do, but would likely cost you much more if they do it.

Another factor that can make slides move slow to the point you think they may quit is low voltage.

It's usually recommended that they be operated with shore power on or with generator running. Engine running in MH or connected to tow vehicle with running engine helps.

In my TT I have LiFePo4 batteries and the gigher voltage even while discharging makes my slide move right along.

Lube of course is a given and it's wise to perform this service both at beginning of season and end before storage.

Mike, the OP did state that he never extends the slide on battery power, only on shore power.

Related Question -
Aren't the items operated by 12 volt power when not connected to shore power still using the 12 volt power when hooked up to shore power? Difference being that with shore power the converter is keeping a charge going to the battery and not letting it deplete itself. And isn't the slide one of the 12 volt powered items just like the electric jack and stabilizers?

So if the battery was going bad and not able to be charged fully, it might make for a slower slide.

Sort of. The converter and battery are both providing power to the trailer. Any excess power not being consumed by trailer components charges the battery.

The typical converter in many trailers is the WFCO 8955 which can provide up to 55 Amps. If the slide requires more than 55 Amps, it will be drawing the battery down as well as consuming the entire output of the converter.

A typical RV hydraulic pump can draw 40-80 amps so, as you suggest, if the battery is low, the pump could indeed be starved, even with shore power.
