Hydraulic jack

3 Ton bottle jack with stand combo should do both.
These are good. I've used them when we had the need.

Here they are: Amazon

Personally I'd get a 12 ton, this is a piece of gear where over capacity is no problem. And you may want to jack up other things. The Torin I can vouch for we have two. Make sure the jack gives enough lift, that gray chinese jack for example does not list the lift of the jack. The Torin 12 ton does 7.5 to 11 inches.

These jacks are available in Lowes and Walmart.

I learned the hard way about bottle jacks when we got a flat on Hwy 2 in MT. At least 10 years ago. The jack I used was a floor jack which jacked the small trailer up OK. But when my son started to remove the tire it dropped the trailer. So use a bottle jack and also jack stands once you have it jacked up. We had a trip to the next town's emergency room where they X-Rayed my sons hand. That's after a local stopped and jacked the trailer up with his bottle jack. I made sure to get a bottle jack at the next opportunity.

and about four pieces of two/by four and a square piece of plywood 12x12. might never use them but there easy to store away.

Ditto on that bottle jacks tend to sink into soft ground.

"that gray chinese jack for example does not list the lift of the jack. The Torin 12 ton does 7.5 to 11 inches."

From the ad for the "gray chinese jack" below the one you're recommending on the same page in your link.

"Highly durable. Wide steel base for stability under load. Height range is 11 inch to 21 inch, but its default lift range is 11 to 17.25 inch, it can be raised to 21 inch if adjusted manually"

And don't kid yourself, they're all made in China.

Good day. I know the answer is likely a simple one but I am just not sure about what I need. We have a single axle travel trailer (max weight 5,000 lbs) and a 2011 Silverado 1500. We recently had a flat tire on our trailer while on the highway so I needed to get out my truck jack to use on the trailer. Thankfully someone pulled up who had a hydraulic jack and they jacked my trailer up in a matter of minutes. This was so much simpler than if I had to get my truck jack all set up. So here is my question. What size of hydraulic jack might you recommend for me to purchase to use not only for my trailer but my truck as well.

Forgot to add, the kind of jack which was used on my trailer was I guess what you would call a floor jack.

Thank you all!

I would be leery of using a "floor jack" (or "racing jack" as some call them) on the side of the road where the surface might be uneven, and the jack could slip or roll, as agesilaus found out "the hard way". Whoever helped you out must have thought the situation was safe enough or acceptable when they used that type of jack to lift your trailer.
The other issue with floor jacks is they tend to weigh a lot more than a bottle jack, particularly as their capacity increases. I also had a 3 ton racing jack from Harbor Freight that easily lifted my Roadtrek when I was doing some work underneath it a few years ago. On a level driveway, with wheels chocked and then used the 3 ton bottle/jack stands to support it. No problems with either product.
All made in China.

Actually they used the bottle jack, I stupidly used the floor jack. And I'm sure they are all made in China, that gray one just made a point of it in the write up.

And heh I found one made in the USA a little pricy tho. But gets great reviews.

I use a Torin 2 stage 2 ton bottle jack with custom handle for my 2 axle 7880 gvwr trailer.
Have used it plenty of times over 15 years. In hindsight I think the 4 ton would have been easier. Just make sure the jack will go under the axle with a flat tire and enough lift to swap on the inflated tire.

Harbor Fright has one version of the 3-ton that lifts 4" higher. A wheel chock is a splendid accessory.

I'd recommend a scissors jack for the job. You need something short to get under the axle with a flat tire. The scissors jack is just the tool for that. They are also a lot more stable than a bottle jack that can sink in the ground and tip over as the load gets heavy when the tire comes off the ground. I see they are also offered in electric models.
