packing bearings

I am supposed to pick up a 2006 yr. TM2619 next week. I am not mechanically inclined. As there are no TrailManor dealerships here in south Florida where I am, where would I take the unit to have bearings packed. Would a regular RV repair place do it?

Is this complicated and costly? What should i expect to have to pay. I want to make sure unit is safe before taking it out.

Do you think I need to get it to a TM dealership to get this work done?
