Joined the Class A family, it's an oldie, hope its a goodie!

Congrats and thanks for sharing. :C

My advice would be, check the roof. Cover joints/seams with Eternabond and/or Dicor Self Leveling Lap Sealant. Address any suspicious areas on the roof to keep it leak free.

Change the oil in the engine and generator. Also, have the transmission serviced.
Then YOU will know when it was done.

It looks like a nice rig. You will get many years out of it.
I like the older RV's, they have more class than the new units.

Enjoy your travels. You will love the Class A.
