strongly suggest your plan for the lift, even if it never comes it will be a possibility,
and to modify the trusses in the future, will
in a corner,of the building, in the concrete consider placing a toilet flange and a 2" pipe for a a sink drain, even possibly a floor drain that could be used for a shower, even if all it does is just exit the building for now, I have a restroom in the barn?shop, and it is used a lot, (I took a play out of the RV book, and placed the floor drain out in front of the toilet, and put in a shower in the toilet/shower stall, (yes it is wise to remove the toilet paper before using the shower, sink is just out side of the shower stall,
in the warm room I have a small apartment stove, a refrigerator, and a microwave, and a large table, when cold it is nice to have a place to work on small things, and stay warm there is even a tv and an easy chair.
draw out or take a sheet of large paper, possibly even graff it out in 1" squares, and draw out the walls of the shop, take light cardboard, and take your floor tools and cut out pieces of the size of them in scale (possibly even better, make a simple model of the items), and your benches, and even a possibly future break room, even the cars and other items you wish to store,
and see how it will fit and to have better idea of how to arrange the layout and how the flow of the building will be,
depending on the trusses and such, there may be room for a storage area above the break room and such,
I realize you have a fair size building but it is amazing on how fast a building can fill up and some times, some planing can save a lot of frustrating in the future,
my shop is smaller but is about 30 x 48, I have sections that are more themed, in purpose, up by the large door is the tire corner, and on the other side is the welding and metal fabrication corner, the back 16 foot of the shop has a floor above it and storage, under the lower part one corner is the machine shop, lathes and milling machine, an a valve grinder, the other corner, is benches and a few work islands (a sharping center for chain saws), and an area for presses and a bench grinder,
in the shed behind the shop is the break room and restroom so in a sense my main show is or only a few feet narrower, than your but about the same depth when you take the sheds in to play, (I have side sheds as well, and one of them is filled with sheet metal equipment,
my entire barn/shop, is a footprint of 60' x 65', (main shop area is 30' by 48') with 16 foot sheds on three sides, and storage area above the 30' x 48' with a second storage area above the back of the shop 16' x 30',
and the wood shop is in another building,
all I am saying it seems and will look larger now, but by the time you put a few cars in it and some tools and other stuff, it will fill up fast,
some planing could be a very good idea, (even just for how to lay out the electrical needs, and where to run air lines, place fire extinguishers, lighting, even the best place to put doors, heating if that is in the plan, even windows,
(my son in law helped build pole buildings at one time, and they were taking about putting in windows, and the guy walking through the building said I want the window right here, so they put the window in right there, outside of the building was huge power pole to look at, LOL)
