I hope that all honest mechanics become millionaires. Unfortunately, I have met so few.
I respectively disagree if you are talking about 'RV mobile repair'. Now Local repair shops well I might have to agree with you! :B
But IMHO not RV Mobile Repair.
When I went full time I found others at CG's using mobile repair for everything fro repairs up to and including maintenance. So I gave it a try and haven't looked back.
For 7 years I exclusively used RV Mobile Repair while on the road. The convenience of it is hands down the only way to go. And I found each and every one I called in every town I traveled thru VERY experienced and very reasonably priced. AND 99% of the time they have the part you need right on board their truck which = same day repair.
When you figure you are paying around 100 bucks an hour for a rv shop and have to leave it for days on end and IMHO and in my few experiences really poor and shoddy work from a low paid tech who is just looking for when its time to punch out. WHY use them?
RV Mobile Repair this is their job, their company and how they make their living. Word of mouth in a CG is what drives their business.
My MH has not seen the inside of repair shop in 7 years. I use RV mobile Repair while I sit back in a lawn chair with a cold one while she's being repaired or serviced. :C
