Releasing Foot Brake after Slides are out?

I hope you're not talking about a MH with an air brake system. Anyway, I'd keep the parking brake set. If you were to release the brake there is the possibility your MH could move slightly and maybe damage your levelers. BTW, most levelers will retract when you start the motor and put the tranny in drive. I had to do that on a brand new Allegro Bus, at work, because I didn't have a clue where the level control panel was (it's now on the glass digital display panel).

So there's some replies on leaving the brake set, now I'd like to hear your reason for not wanting it set.

If Diesel with Air brake, it will not release when the jacks are extended. When you do a correct level with a Diesel, you dump the air Bags and then level. Once the Jacks hit the ground and raise the RV, the remaining air in the Air tanks will bleed out from the ride height arms and you have insufficient air to release the Parking Brake. Doug

I have never done this but I have a Monaco DP and on several occasions the parking brake did not release. It was determined to be because it had metallic brake shoes that had “froze” to the drums. Easily released by hitting the throttle in reverse. But I still leave it applied when parked.

Why would you want to release the parking brake , on a vehicle so large, with slides extended out like sails, you could end up rolling thru the campground, most likely into another camper

Powergear system and some LCI will release when the parking Brake is released, BUT, the key has to be turned on. If camped and the Ignition OFF, and you release, the jacks should not retract. If they do, the wiring is not to spec. Doug

You are correct and I failed to mention the key being on !

I was thinking of when he got in the
Drivers seat preparing to leave, turn on the key to power up the slides and because the parking brake has already been released the jacks retract, but the slides are out, he would no longer be level, and any good wind would be putting additional strain on the transmission parking paw ,
This is not a situation I would trust, This could damage the transmission if the MH moved,
Even more dangerous if the MH has kick down jacks, which have been know to give way and flip up, if the RV rolls forward, it's a feature which prevents damage to the jacks, if the RV is driven forward while the jacks are down
How ever it might be described, I think releasing the parking brake , while using leveling jacks and slides ,
Is Bad Idea
There is nothing in the chassis literature that says do Not use parking brake for ???? Or longer tHan xxx

PARKED STORED NOT BEING MOVED parking brake should be engaged
