Old post,but haven't been on here in a long time
I can understand the resentment or dislike of back yarders but as a current Mobile Tech and shop owner I ask that you don't lump us all together. I run my Mobile business with full insurance, business licenses and taxes, I offer warranties, and quality repairs JUST like in the shop. Granted I can't do it all like a regular fixed structure shop on "the road" but I can tow it back and do it in the shop. I offer rates close to what the other local shops charge,just a little less because of the low overhead I have.
Having said the above, I know of one other legit mobile business in my area (Lic, taxes, insurance etc...) and few other ones that make your average DIYer look like professionals. I guess I'm saying don't judge us all because of a few bad apples. Hell, regular shops get judged like this too and we all hate that!
Not starting a war here just wanted to vent and hopefully stand up for the good ones. Hope all are having a good day/night. Be safe!
