while your garage is 45' deep im looking into building a 20X42 and was wondering if its enough room to park 2 full size suv's (Cadillac escalade esv the big one) one in front of the other ?
Tough question... I have a dodge ram quad cab 1500 and with it in one end it reaches to my heater (which is exactly halfway). I bet you could, but you wouldn't have a ton of room to move around. Wikipedia says the Escalade ESV is approx 18' 6". Depending on how long your other SUV is you should be OK. Just not a lot of wiggle room.
