Moving, going to need to build a garage

Just saw this and wanted to add my thoughts.... Built mine in 2008...40x30... Two, 10'wide x15'high roll up doors.. Can pull my mh inside... Can't close the door but still have most of it inside...Rollup doors are self storing.. You don't lose any height inside... Put in all the fluorescent lights in you can get. Split them on more than one switch... That way you only have to light where you are working... seal the floor with a good epoxy... Spills or leaks will wipe up very easily... You being in Texas might want to re-think no air.... I put a five ton system in mine and it's the second best thing I did... The first best was my lift... I'm getting too old to work on a creeper and under jack stands... Especially during the summer heat and humidity... With the air just knocking the temps down ten or fifteen degrees and the humidity down twenty or thirty percent can make working in the garage fun again... Add the lift and even at 64 it's fun again!!!! Build it as large as you can... I would love to have mine 40 x 60.... Bit too late now. I thought mine would be way more than enough.... But I have to make do........
