campernurse2012,
As Padget said, you probably have a #10 Dexter 3500lb axle on your 2005 TM2619. Here is the service manual:

Forget about the painted over paper on the axle. The axle's nine digit serial number should be permanently stamped into the axle near the center on the rear side of the axle (See pg. 88 in the service manual).
In addition to the serial number, there should be more information about your axle that is also permanently stamped into the axle (no paper). For an example of this on my 2007 TM 2619 see #6 post on this thread:

Hope this helps.
