The GMC van that went into the water as the A Team was escaping turned into a late model Ford Econoline van when it was fished out.
When the car carrier is seen as an escape route there is a prominent white car on the top deck that goes missing less than a second later, as Hannibal drives up the ramp the inside shot clearly shows the car but the underneath shot clearly shows an unbroken car ride that should be impossible had the car been there also the exterior shot shows the car missing.
The report being read by Col. Decker details previous escapades of the A-Team (from earlier episodes), starting December 3rd 1977, however we know from the title sequence of Season One that they escaped "10 years ago" and from subsequent seasons' title sequences that they escaped "in 1972", meaning all scenes in all seasons are set no earlier than 1982.
Around 0:21:14, during the chase-scene in tunnels, the camera mount on the side of the car is clearly visible.
The entire California and Arizona border is the Colorado River. The state line is depicted in a place where there is no river in sight.
