Simply take it back to the dealer so the service manager can tell you "we're really swamped now so leave it, and we'll get to it around the middle of July."

Hopefully this can be corrected by swapping some wires.


Hoses, not wires....The Heartland we just bought has 3 slides, and this is my first rodeo with hydraulic. After the short time we've owned it I can tell you I will never go back to electric-driven rack and pinion. Our sequence is street side bedroom slide, curb side main slide, street side kitchen slide. As Doug said, the hydraulic lines are plumbed that way....when slide 1 is almost home (either in or out), pressure builds and starts moving slide 2, etc. When retracting the slides they go in the same order, not reverse order. Doug knows the most about this, but I think the only way to change the order is to re-route the hydraulic lines and change the order in which the slides are connected from the pump.

BurbMan and Lantley, after Doug's post, I am hoping the sequence can be a simple swap of hydraulic lines (or something similar). Yes, the curb slide should definitely move first.
If the sequence can be reversed, I will be a happy camper.

Chad of changinglanesRV.com has a Momentum and has a mod that permits extension of one slide.

Thanks. I will look into that.

Edit: Just watched a video of his. I can close 2 valves in a propane compartment to make just the curb side open. That will help. But I would still like to reverse the sequence if that is possible.

Changing lines won't change sequence. Lightest or least resistance goes out first. Heaviest last. Same on retraction lightest first heaviest last. Pump is pushing fluid to all 3 cylinders at the same time. Not sure if used anymore but some units a few years back had a manifold near the hyd pump with manual valves you could block off individual slides.

That certainly makes sense. But our fridge/oven/pantry/TV slide goes out before dinette/theater seat slide. I would have expected the fridge slide to be heaviest.

Mine are opposite, the dinette/seating slide goes out before the fridge/oven slide. Maybe those theatre seats weigh more than you think?

I found this YouTube Video of how you can control slides individually on a Grand Design, see if yours has these fluid control knobs. This may be all you need!

Maybe you could add some resistance to the slide you want to open last.
