Venturer Posted November 27, 2023 Share Posted November 27, 2023 (edited) Where are the jacking/lift points on the Roadmaster chassis with air leveling? I assume the axles, but does one rely on the air bags to remain inflated to change a tire? Edited November 27, 2023 by Venturer Link to comment Share on other sites More sharing options...

Dr4Film Posted November 27, 2023 Share Posted November 27, 2023 When changing tires they lift on the axles evenly from side to side so the body doesn't get tweak. You can raise the body on the air bags then block the frame from the chassis to prevent it from lowering. 1 Link to comment Share on other sites More sharing options...
Venturer Posted November 28, 2023 Author Share Posted November 28, 2023 Thanks. It was the chassis to frame area to block that I was wondering about. I won't be doing any changing, however, I want to know where in the event it's needed. I'd like to know it's being done correctly and safely. 1 Link to comment Share on other sites More sharing options...
Guest Ray Davis Posted November 28, 2023 Share Posted November 28, 2023 Some guys want to put a jack in the center of the axle & lift both sides with one jack, don't let them do that, it can bend an axle. Even the front axle. Link to comment Share on other sites More sharing options...

Even the front axle. X2 on this, unstable and the coach could tilt. When I had my tires changed they used two bottle jacks, one under each side. 1 Link to comment Share on other sites More sharing options...
Venturer Posted November 28, 2023 Author Share Posted November 28, 2023 (edited) Then you rely on the air suspension to keep the body up? There must be body support places to support it for changing air bags. Edited November 28, 2023 by Venturer Link to comment Share on other sites More sharing options...
dl_racing427 Posted November 28, 2023 Share Posted November 28, 2023 My coach has jacks instead of air leveling. For long term storage, I raise it on the jacks, and place properly rated jack stands under the chassis, then retract the jacks to protect the rams from corrosion. This keeps weight off the airbags and tires, and to lift a tire only requires a regular floor jack under the axle. Look for points on the chassis that the suspension ties into, and that have vertical members running up to the main rails for strength. Link to comment Share on other sites More sharing options...
Venturer Posted November 28, 2023 Author Share Posted November 28, 2023 Thanks, I'll do some searching. After several coaches, this is my first one without jacks and my first Roadmaster chassis. 1 Link to comment Share on other sites More sharing options...
MHRookie Posted November 29, 2023 Share Posted November 29, 2023 You don’t need to support between the chassis & house frame to change tires. As mentioned, the use of 2 jacks is most important to lift coach equally on both sides under the axle. 1 Link to comment Share on other sites More sharing options...

However, I like to use a safety backup for the "just in case" event a jack would fail. I don't want the body coming down on myself or a service man. Maybe it's not needed, but it only takes one time to ruin one's day, or worse. 1 Link to comment Share on other sites More sharing options...
Michael Powell Posted November 29, 2023 Share Posted November 29, 2023 I made 8ea 2x2 square tubes with saddle on each end and put them next to each air bag then lower the coach on them... When I get back to the toy barn I will take pictures of them with measurements. Seam to work great... 3 Link to comment Share on other sites More sharing options...

When I get under the coach, I drive it up on "DIY" ramps or I would really prefer the square tube method that Michael will be providing us when he gets pictures posted.

Venturer Posted November 29, 2023 Author Share Posted November 29, 2023 Thanks. I've built the ramps in the past, but they're gone. The square tube support sounds like the answer to what I want. 1 Link to comment Share on other sites More sharing options...
Dr4Film Posted November 29, 2023 Share Posted November 29, 2023 I have two one foot sections of PT 4x4 which I place between the rails and the frame body after it has been raised up on the air bags. I release the air from the bags which secures the 4x4 in place. That allows me to easily crawl under the coach and work on various locations. 2 Link to comment Share on other sites More sharing options...

Twomed Posted January 1 Share Posted January 1 4 inch square tube 5/16 wall 11 inches tall. Two points having had mine for 15 years now. A)I know and saw 4x wood split...not mine B) A friend made his 12...with just a little uneven ground one side got stuck. Hyd jack in there to get a little lift...not fun. C) This info for tag axle RR10 chassis only. D) They fit neatly laid down next to the 150 gallon fuel tank so you can have fun on the road occasionally too!

Trevor and Laura Posted January 2 Share Posted January 2 Thank You for the pictures and description, did you consider using thinner tubing, 5/16in seems prtetty hefty, but no doubt very safe. Regards, Trevor Link to comment Share on other sites More sharing options...
