^ is correct.
1) the ride height is a specific measurement set by the chassis manufacture and is usually a distance between the axle and the frame. In my case it is 7 1/2 inches in the front.
I looked for a picture showing the body height with the bags inflated to ride height, and found this one. The shadow makes it very hard to tell, but I have room to crawl under the bus on my back and have a inch to spare (I'm a big guy). If you look at the front it should give you an idea.
This is the Room in the wheel well and I have over size tires (295/75/22.5)
2) If the motor home has been sitting on the lot it most likely has lost air to the suspension. This should not happen, but with the age (mine is a 97) it is common. When I purchased my motor home the first thing I did was replace all the air bags and then all the ride height sensors. The motor home would sit for a month and not lose pressure.
3) This past summer that changed and would lose pressure over night. I had a truck place look for the leak and it got extensive. Even pulled the air compressor and the descant air cleaner. I finally found the leak in the sensors under the dash and that was a simple fix.
Low Air Pressure Senor Replacement
4) I do not want to scare you away, the American Coaches are a "1,000,000 mile" chassis and have a drive train to match. Routine maintenance is critical. Don't buy a coach that does not have all the manuals (they are extensive) and maintenance records.
5) I have started to put to gather a list of things to before leaving a dealership (common question and got tired of writing it over and over) after a purchase, you might get some ideas of what to look for when considering a unit from the list
Do not leave the Dealership until you have been shown how to use your Motor Home.
This should include checking the fluids in your engine, running the Motor Home on shore power, being explained how to dump both the black and gray water tanks, make sure you have a hose to connect to the dump fixture and the dump port in the ground, run the internal 12 volt water pump, have them explain how to hook up to city water, run the furnaces, check the level in the batteries, run the jacks / leveling system, in the driver’s seat go over all the controls (put you hand on each one and operate it) , run the dash A/C, run the ceiling A/C units, make sure you water comes out of the faucets (check that you make hot water), run the micro wave, stove, oven, check all the lights, work the toilet, Shower, review the charging, solar, monitoring system, run the washer dryer.
There may be more and I’m sure someone will check in with something else.
The big thing is do NOT let them rush you out, the time to ask questions is before you leave, once you leave getting answers gets much harder.
If you do a good job here I’m sure you will find faults and get the promise that they will fix the problems in writing.
If you spend an hour you have not done it right, four hours is more like it.
6) I would say I have had to do a lot of work to get mine to a point where I trust it. Most of that was because I did not buy smart. I bought it because I liked the way it looked. In my signature is my projects thread, take a look. Remember I did not buy smart.
7) found two more pictures see below of the motor home sitting at ride height
8) I would be surprised if it had any problems getting up the driveway, it would really have to have some abrupt incline changes to cause a problem.
9) Feel free to ask questions this is a great forum with lots of information.
