Broken Leaf Spring

Discovered a broken spring pack when we arrived at the campground. Called a local RV place and obtained a replacement. Now, to replace it my BIL thought we could pull the other wheel up on a ramp he has and with one of my two bottle jacks we could work the broken one off for replacement.
I would rather jack the frame up on that side and, with the wheel removed, replace it.
We're both mechanically inclined and have the tools necessary, including lots of 2X12, 4X4 and 6X6 wood to crib the frame up.
What are your thoughts as to the best method?

TIA.

P.S. just wish I had brought my impact gun and power ratchet!

..........The best jack I've found is a 20 ton , hyd. jack with the air powered option ! Squirt some 20 wt. oil into the air line before connecting up to pressure as it will enhance the pulsing mechanism lifting the jack . These jacks are available @ Northern Tool as well as Harbor Freight .
..........I placed the jack immediately behind the back hanger to lift one side of the trailer............Also , trailer was connected to truck and landing jacks were raised and not used ! Did , you know the length of the eye to eye measurement of your spring packs , Before you removed them ? IF , your center to center distance on your axles is 33 inches , your eye to eye distance should be 25 1\4" inches ! Most 5'ver owners have NO idea what this number is !
..........IF , a 5'ver has a broken spring pack , one axle can slide back causing the tires to rub against each other which will cause them to catch fire in short order . A tire on fire is a difficult thing to put out . , jf
