Jacks for Rigs

I'm not sure how large a bottle jack or whatever is the best to use. I was thinking about a 20 ton jack would be good. What do you all use to jack up your TV and or Monties, to change tires etc? Thanks Randye

Randye,

Remember the greater the tonnage, the heavier the jack. My 8 ton bottle jack will lift both one side of any axle or both axles on either side.

Mine also is 8 ton. Walmart has them in that size.

--on edit-- saw mine today. It's 6 ton, not 8.

My friend had a flat on a 5ver a couple of months ago and didn't have a jack with him so he used around 5 2x6's he had in the rig and drove the front tire up on the blocks to raise the rear tires he said it work fine. During a recent web search for leaf springs I ran across this site, and someone has come up with a better version on using 2x6's. Here's the link and would be interested to know what people thought of it, look simple enough to build.

I use one of those emergency road service outfits. Only time I had a blowout, I was back on the road within 90 minutes. (I am going to buy a 8 ton jack however.)

I use a 6 ton, and wish I had bought an 8 or 12. It will lift what I need, but it's pretty hard to work from a prone position.

We carry an 8 ton bottle jack in the rig. That means 16,000lbs and the 3400RL does not weight that amount and I am not attempting to lift the whole unit.

I have a 6 ton bottle jack from Harbor Freight...since I'll never lift more than one of the four wheels, 12,000 lbs should be plenty.

I also carry a 12 ton bottle jack purchased at Harbor Frieght. I considered the blockage idea but almost immediately reconsidered. When pulling onto blocks with just one tire and lifting the other off the ground puts all the weight on one tire. Maybe for a quick flat tire change this may work but there is no way I want to crawl under that rig with all the weight on one tire. I would suggest getting the spare out from under BEFORE pulling up on blockage. If the supporting tire fails you'd have a serious problem especially if you were under the rig adjusting the brakes or whatever. I was in the tire business too many years and I have seen it done and have seen the results of a tire or spring failure. My 12 ton bottle jack cost me 39.95. I'd rather be safe than sorry.

Also when jacking up the Monty, It is advisable to have the Monty hooked up to the TV for a number of reasons....
#1- To get the weight transfer onto the hitch and NOT on the front jacks.
#2- Set the TV's emergency brake to avoid ANY possibility of the Monty drifting. You are still advised to chock the Monty's wheels front and rear.
Never ever jack the Monty up while still on the front Bi/Tripod. This is a good way to destroy a Bi/Tripod.
Also have the rear stabilizers up and not touching the ground to avoid any undo strain on the stabilizers.
Only jack the Monty up to take the weight off the tire in order to first loosen the lug nuts. After loosening the lug nuts, jack the Monty up just high enough so as to get the subject tire off the ground. Any higher will start twisting the frame.

BTW, Harbor Freight had that same 12 ton bottle jack on sale 2 weeks later for under 20 bucks.

You need a good bottle jack if you have a flat on the rear of the truck while hooked up to the Montana. Just try that factory screw jack and see what fun it becomes.

Excellent point Dennis. No way would I want to even think about jacking the TV and the Monty at the same time without my 12 ton jack.
