I see all sorts of replys as what not to do. Does any one know how to raise the MH to change tires?

Doug, why can't we raise our MHs with the hydraulic leveling jacks to change the tires? Most leveling jacks are rated for the weight of the coach. One would think that the frame mounting locations shouldn't be a problem. We all know jack stands are required.

Because the only thing keeping that RV up is hydraulic line pressure. If the line burst or a solenoid failed, or even if a jack mount plate broke loose, the RV would come crashing down in about 2 seconds and anything/anybody under or close by can be hurt or killed. If you do raise the RV with leveling jacks, install jack stands to support the RV if the jacks fail. BTW, I have experienced all 3 failures I listed above. NOT changing tires, just a failure of the jack system. NOT even a good idea to raise the RV with the jacks and crawl around underneath. You see reports all the time from people dying working on their Cars at home with no one around and the floor jack failed and the Car crushed them. AND, ALL the Leveling Jack manuals state to NOT change tires with the jacks(CYA). Doug

Thanks Doug,

As you and I both know, jack stands are absolutely mandatory.
It looks like your concern is hydraulic pressure failure, which I agree with. I had hydraulic line failure when trying to lift my coach off the jack stands. I was stuck there until I replaced all the old lines.
