Welcome! You should be in for a lot of good times and good memories.
If by early spring you mean in freezing weather, that may drive some different requirements for your trailer than otherwise (depending partly what direction you're heading). Many travel trailer water systems are not well or at all set up for operation in sub-freezing weather.
If possible, I suggest having your first camping trip with the trailer in your own driveway. That gives you a chance to figure out how things work and to find the nearly inevitable forgotten important item or two.
