Speedco for annual service, but with the help of generous folks on this list and YouTube, I have done most of the other maintenance the past five years.
Replaced the water pump, changed the tube TV to a flat screen, replaced the water heater, replaced the satellite dish with HD, replaced the solar panel with two 100 watt panels, recoated the roof, Eternabonded the roof seams, replaced most of the filters, replaced the Norcold 1200 cooling unit with an Amish unit, replaced the CU propane nozzle, replaced the retracting step unit, installed the TPMS, replaced the front power screen mounts.
Most of the readers here could do this and some could do much more. If you are a motorhomer, I think it is good to be able to do most of your own maintenance, except for major engine, transmission or chassis work.
I did have an RV mechanic set up my M&G and Demco baseplate on the Buick and set up the wiring and air connections on the motorhome.
