Leveling jacks

I have a 1982 Excella 28 with the Isuzu diesel. A member has an HWH set up for sale and I'm trying to find out if his system will fit on my coach. Can anybody tell me where the jacks are mounted on a 28' and what kind of jacks are used? Pictures would be great. I realize the control system and pump can be set up easily but I'm concerned about the jacks themselves.

Thanks, Dan

Hi, Dan - we tried that on our '82 and finally gave up. AS manufactured a big frame-like thing to go under the coach just in front of the rear wheels. The jacks mounted to that and the whole mess was welded to the frame before the body was put on. Then the jack mfg said NO to mounting the rear jacks in front of the rear wheels. Seems jacks should go behind the rear wheels and as close to the front wheels as possible. Good luck, anyway. - Jamie

Jamie do you actually have a mount welded to the frame ahead of the rear axle? I put jack stands there to work under the coach once and the frame flexed so much the door wouldn't close.

I have been looking at the HWH site and there are a couple of mounts (these are the flip up jacks) that go behind the rear axle. My concern is the fuel tank and mount hang down about a foot below the frame rails and it gets pretty tight to fit the jack. I don't know if the gas unit has the same tank as the diesel.

I was hoping to see what others have done so I can get it right the first time rather than by trial and error.

Thanks, Dan

Not sure if this is what you need but let me know

if I can take different pictures in daylight. It's close to sunset now and without a flash this is the best I can do. I am not sure what you need pictures of, so I put down the jacks and this is what it looks like underneath in the rear. I'm also not sure if ours are as down as they should be--they look a little cockeyed.

Jamie,

I'm a little confused here. Our 84 310 has the rear jacks located in front of the rear axle. I don't know if Airstream installed the leveling system or if some previous owner did.

I do know we can get the chassis twisted enough with the jacks down that the door doesn't open but its not hard to get the coach leveled with them and still have the door function just fine.

Brad

Swanky, If I understand your pictures it looks like the jacks are mounted to the rear of the fuel tank. HWH is indicating the jacks should be at or near the rear spring hanger. With the air suspension there is no rear spring hanger but if there was it would be forward of the fuel tank. Do you know the brand of you jacks?

It seems what I am seeing is that the jacks are mounted all over the rear of the chassis. Maybe there is no right or wrong just whatever the guy who mounted them thought was easiest.

Thanks for the help, Dan

I'm sorry, I have no idea whatsoever.

I'll get back under there tomorrow and see what I can see and take some more and maybe better photos. I can also tell you what the switch box says in case that tells anything. I am 100% blonde on this one. Sorry.

Yes, there is a welded boxy frame set just in front of the rear wheels with the jacks mounted to it. That was an AS "invention" to reduce the body flexing problem. The HWH solution you mention is the correct way, but hard to do on an Airstream classic coach.

Not meaning to hijack this thread but your Smart42 looks like a great Toad for your coach.

Zoomin I can't speak for others about a hijack but I love smart cars and will chat about them anytime. I bought my first smart in April 06 and loved it so much I bought a second smart in April 07. They are great little cars and they make great toads. you don't even know it's back there.

Cheers, Dan

Hey there Dan, I hope someone on this Forum can help you with your original question. That aside, I have more fun in my Smart than any of my other vehicles, Corvette included. We can't be bashful in those Smart42's now can we? Folks love to come over and talk about ours. What a hoot. Good luck with your coach mods. Lots of 'smart' folks on this Forum and most helpful as well.

Yes behind fuel tank

there is a metal crossbar that has been attached to what look like I beams that run from front to back on either side inside the wheels. Does that make sense? Looks like an addition to me. In all the commotion I have forgotten the name on the inside contoller. Will check tomorrow.

jacks

Yes swanky that makes sense that they added a cross member to the fore and aft frame rails to support the jacks. I'm surprised that they are mounted so far to the back or the coach. It looks like they have worked for many years so I guess it must be alright.

Where is your controller mounted? Is it along side the drivers seat, on the floor or up under the dash. I guess that it another decision I will have to make.

Thanks for looking, Dan

OT but I'd like to know if you tow your smart 4 down? Who makes a base plate for them?

What kind of mileage do you get in the smart?
