electric hydraulic lifts to change tires
I have a 98 Born Free rv and was wondering if there are any electric lifts that could help me change a tire, along with a 3/4 pneumatic wrench.

From Harbor Fright, you can get an air-over-hydraulic jack
that will run off your tire-inflating air compressor at 110-120 PSI.
While your campground pedestal or onboard genset is supplying the compressor, it can let you also use a 120 volt impact wrench
HF doesn't sell the 7/8" deep impact socket you need for E-Series wheels. I ordered mine from Amazon.
I doubt that EITHER items will be "usable" with a 12V powered compressor or even a small "pancake" 120V compressor with a small tank..
HF doesn't give CFMs for the jack but I suspect it will NEED more CFMs than most small compressors will be able to supply..
The air impact is a definite no way, not gonna happen at all with any small compressors.. It will need a compressor that can supply 110 psi- 120 psi at a min of 7 CFM, MORE CFM capacity is better..
I have a 4 cylinder Emglow compressor with a 5 HP electric motor which can deliver 20 CFM and a bit higher and using a 1/2" air impact makes it run a lot..
