Stop in for a cup of coffee
And just to muddy the water, as someone with a two post I will never go back to a 4 post! I think perhaps that question has no better ending than the infamous what cam do I use question!
They both have their place.
I dont care for the 2 post,from a safety standpoint, balancing different vehicles can be a challenge. Setup was a pet peeve, crawling around trying to line up the ams in the right places.
Cant fix rockers,or safely strip a car down to the shell without adding supports.
4 post-
Front end work is a ***** on 4 post compared to a 2. Still do-able. Without jack trays or bridge jacks pulling wheels is near impossible.
They take up a lot of space.
4 post needs more maintenance and regular adjustments. Deck is dirty all the time.
Engine bay is 6-7 inches higher, working on a big wheel truck requires a good step in order to reach inside engine bay.
Pulling an engine is more difficult,the legs have to go under the hoist.
I can go on and on about disadvantages with both hoists,but i will use a 4 post before a 2 post any day.
Have been hoisting vehicles on 2 and 4 post for 20 plus years and i just feel safer using a drive on.
