After launch notice no cold side of Dometic AC system. Heat works, good pressure out of discharge so couldn't be intake. Any suggestions would be appreciated on what to check for next?

Sounds like the reversing valve is stuck. Find it on the unit. tap gently, while calling for AC, with small hammer etc.

Possibly a leak of the coolant or it may need to be recharged? Not sure how old your system is? I just replaced a 12,000 BTU unit with a new Dometic and the new system is all self contained with no place to recharge the unit. The previous owner had let the drain get clogged and the pan and underside of the Freon tank and cooling coil fins had rotted out. Now the new ones are all hard plastic.

Either reversing valve is stuck or signal is not getting through from thermostat.

The unit is an '08. I'd like to try and 'tap' the reversing valve as bahamabreisus suggested. I tried googling for an image of where it's located but no luck. If someone finds an image, please send link. Thanks!
