Re: Can I store my MH with the leveling jacks depoloyed?
Let me suggest that if you contact someone to ask, make it the company that built the jacks.
As to storage with the jacks down, if that were bad for them, what value would jacks be to those of us who are fulltimers? We sit with our jacks down all of the time except the actual driving hours! Any well made leveling jack should have the shafts made of something that will withstand the weather. We have jacks from Big Foot and ours are now nearing 12 years old and 10 years of that has been with us living all of the time in the RV. We travel for a month or two and then we sit in one spot for anywhere from one to four months and our longest was five months. And we don't park with the jacks up!
In our experience, we have had on position indicator fail, which I replaced with a part sold to me direct from Big Foot, two jacks have had a solenoid fail and again I replaced the part, from that same source. Last spring, since we were passing near the Florida location for Big Foot, I stopped in and had then go through all four jacks and check and replace everything they felt might be needed and it took just over five hours and the total cost was less than $300. Not bad for 11 year old jacks, I'd think.
There is absolutely nothing to be gained by storing with the jacks up, if you follow the manufacturer's instructions. And there is something to be gained for your suspension by relieving it of a major share of the weight that would otherwise be compressing it. If you talk with the jack techs, I am sure that they will confirm what I have told you. It was the Big Foot support folks where I got my instructions and advice.
