Noisy slideout

mine do a lot of squeeling even after spraying greasing and everything else I can do

Two noise sources on slideouts:

The sweeps along the side of the slideouts will squeal against the siding depending on how dry the siding is. There is a spray on coating to stop the squeal.

The slide mechanism depending on what it is (mechanical or hydraulic) may squeak, rattle, clink, click, motor/gear grinding...etc. Usually lubrication will quiet this down.

On our 5th wheel a piece of sheet metal was contacting the slideout ram and made a terrible noise (AKA-fingernails on chalkboard) until I discovered the piece of metal and bent it away from the ram.

So yes just like garage door openers there will be some noise when using opening or closing the slideout. I would compare it with other models at the dealer to see if the sounds are similar.

"mine do a lot of squeeling even after spraying greasing and everything else I can do" - OK so this is very normal then it sounds like. Was yours like that from the beginning?

That's super helpful. Thank you!

I use a dry lube spray on the teeth under the slide, which in turn gets onto the gears. I use talcum powder/baby powder on the wiper surfaces, except for the outsides facing the elements. On outside wiper surface, I use RV seal conditioner, to keep them soft and pliable. I use Protect All on the slide side surface, to keep it slippery. Yes, I do the slide side windows and frames as well. Every little thing can help for smoother/quieter function.

Tip: Do not leave ladder legs in the way when closing slide! (don't ask)

It's is going to be impossible for someone on this forum to tell you whether the noise is normal or not. No one on here can hear it and a salesman will tell you whatever.
Do they make noise - yes. However "very noisy, squeaky and squealy" doesn't sound normal to me. Maybe your exaggerating what you are hearing but better yet have someone you know and trust (that has an RV with slides) give you an second opinion.

I'd have them go ahead and lube the slides see what it sounds like after that - BEFORE you take delivery.

Yep - transport driver is checking it out for me. I do intend to keep everything lubed and checked regularly. Just wanting to avoid major problems from the get-go.
It's a gorgeous fall day here in Western WA. Hope you are enjoying yours!

Yes they make noise. Congrats on your new camper!

Thank you!!
