Can I "pop up" halfway

[Ksolsberg]

Just brought our new 1207 home and I want to learn more and explore the inside. The ceiling in our garage is 9' so with the AC unit I can't open it all the way. Will it hurt it to open it as high as possible, pull the beds out but not put the pole in above the beds?
All I want to do is see where all the storage is, possibly seal any openings in the floor (heard about mice on here) and just feel my way around.

We've owned two Rockwood PUPs and now have a Flagstaff. I've popped them up halfway in the garage several times. Some times just to dry out after coming home wet and still rainning for days. I would think that the Jayco wouldn't be any different. Just be careful not to force anything that doesn't want to move easily (this applies to popping up outside too).

Congrats on the new camper.

We have popped ours up just halfway for one reason or another. Just be careful when sliding the beds back in b/c sometimes they get caught when you don't have it up all the way. Yours will be popped up nearly full though so you should be fine.

When only lifted half way the corners of the beds on our Dutchmen pop up would catch on the canvas. Tore the plastic of one of the windows and had to send it out for repair. Be careful and watch everything when closing up. Also, remember that there are no safety supports holding the roof up (at least on ours) when open only halfway, so if the lift cable breaks the roof slams down on your head.

With the Jayco lifter system you wont have to worry about it falling on your head it locks in place with every click. Do not get on the the beds without the support bars in place though it will bend the bed slide rails.

My pup is in the garage for the last 3 days half up, done it in the past as well, great way to dry / air it out.. It's a Jayco. Can't speak to other manufacturers

I have done this as well but I did make a couple of two by fours cut to the same length to use as supports. This will take the stress off the cable.
