The unit may or may not have had a leak. It can be checked for correct freon charge by using a clamp-on amp meter. I won't go into the process here, but someone who claims to be a RV tech should know how to do it. It's the same for both Coleman and Dometic. If it does have low charge, then it does have a leak and that must be repaired, a service port sweated into the suction line and the unit recharged. Whether it's feasible to repair depends on where the leak is. If it's a matter of some tubing rubbing on something and wearing a pin hole, that's easily soldered and the unit should be saved. If it turns out to be in the coil or condenser, then you have to figure the cost of parts(high), and the shop labor rate($100+/hr) and decide from there. I usually recommend replacing the unit if the cost is going to exceed half the cost of a new one. Older units are not worth fixing, but I would certainly get a second opinion before trashing an AC that is only three years old.
