floor jack or bottle jack or better idea?

[jamesbehave]

So I've got a nice old AmGen that that needs a big'ol water tank put in. I'm going to have to lift the bus some to get the frame welded in- now I've been seeing all sorts of enormous numbers like $1500 for a 10ton floor jack and at the other end of the spectrum $50 bucks for a bottle jack....
the only bus I've ever owned prior to this was a 1979 vw bus, so this is a whole new world....
any ideas or advice for a jack???
thanks in advance ladies and gents!

I have a 20ton bottle jack for my Class C.

Last road service I called in, the guy who came to the rescue had one similar to this .

Being pneumatic, you just squeeze the trigger and watch it jack. No good for on the road type use unless you have a compressor, but in a garage.... I can see this thing being used.

I have no garage and a too small compressor or I would already have one.

I have a collection of jacks,, Mostly bottle but in the towed I have a low-capacity floor jack.. This one is absolutly fantastic for changing tires... ON THE TOWED. however if I tried to lift the motor home with it it would more than likely blow it's seals at me...That's if I'm lucky (It has about enough lift to pick up the tire... NOT the axle, but the TIRE, and rim)

If I need to pick up the Motor home, one corner at a time I use one of these:

Jack from harbor Freight

I just plug it into my air compressor and a couple of tanks of air later.. I slip a jackstand under the axle

If you are going to use one of these either lay plank under the wheels and lower it back down, or use jack stands.. I can not stress this enough.

(The last time I picked up the rig with this jack it slipped.. No injury, No damage, but if I'd not used proper safety measures.. The outcome would not have been ncie at all.. The outcome.. Re-positioned the jack and success the 2nd time)

I wouldn't jack it at all

It sounds like you're going to be doing some work under there, and there isn't a jack in the world that I'd trust to lift and hold my - whatever - while I'm under it. The only way to jack it safely and work under there is to also have jack STANDS in place. They too have to be rated to carry the weight though.

What I'd do instead of a jack it is to drive your rig up on ramps ( correctly sized ). Your rig will still be evenly supported and will be much safer. The ramps will lift your rig up about a foot - about the same as a jack. You can get some nice plastic style ramps just about anywhere. I've even seen them at Walmart.

The target vehicle is a full sized bus as I understand it. Those ramps don't stand a chance.

You are absolutely correct about jackstands though, even if you ramp. A failed ramp will give you about 1/4 second to get out from under the vehicle. I saw one fail, and thank God nobody was under it. We were taking a lunch break at the time and the vehicle was extremely unstable on the remaining ramps until we got the jack out. We used the stands with no ramps after that.

FWIW it was a 1972 Chevy 4X4 Pickup and were changing out a bad transmission.

One of the things I love about my Damon is that most of the "Under" jobs, I can do with no jacks, stands. or ramps at all.

Even at 330 pounds (Which is more than I now weigh) I was able to crawl around under it with the rig sitting on the ground, Jacks retracted.

Handy when the blasted chassis battery needs cleaning

[jamesbehave]

You are correct in that I need to do work underneath, to be specific:

I need to get a water tank under the bus - a 210 gallon

I would with out a doubt be using stands, I have just seen crazy prices on floor jacks and was hoping there was a cheaper way to get equipped with some kind of jack for this work and incase I ever needed (when I need) to change a bad tire.
Thanks for everyones input and keep it coming.

P.S. anyone have anything bad to say about "Shur-flo" pumps?

[seilerbird]

Personally I would pay someone else to put in the water tank and not mess with it myself. I would consider it money well spent, and probably cheaper than buying jacks and stands.

It's all a matter of preference. Some of us like to get dirty and some do not. Most DIY people enjoy the challenge of mind and muscle.

The hardest I was ever involved in was putting a Ford 5.0 in a 1974 Mazda RX4. What a screamer.
