Recreational vehicle repair. Sales are way up since the industry almost died after 2007/2008, and the manufacturers are producing crap quality in order to satisfy sales demand. It's not uncommon for someone to spend $400k on a new RV and have to take their new purchase back for a months worth of rework -- only to find out there's no service openings for 5 months.
What's stopping me is the up-front capital requirements to lease a building, hire technicians, and buy the tools & equipment needed (you can't just use an ordinary car lift on a 50,000 pound bus).
I have thought about this too along with selling the house and going full time in the RV.
One interesting sub-niche of this is RV solar installation, this seems to be booming as well with few who know how to do it right. AMSolar is the premier one and are booked solid months out.
Mobile RV repair is extremely common and doesn't have quite the same capital requirements. The challenge is getting set up with a manufacturer to be a warranty specialist. Most of the warranty work required is interior stuff anyway like plumbing, electrical work, cabinet and door re-hanging, re-carpetting, etc. Leave the "roof replacement" jobs to the big shops and you could get started quicker than you think.
Yeah, I wouldn't do things like glass replacement - even as a shop owner I would call the vendor for that. So far as getting certified for warranty work from WBGO or Newmar, etc. I would think they'd want you to have a bricks & sticks location. Not sure yet.
Pretty fantastic. We're stationary for the winter with the RV in storage (my wife is working at a ski resort and I go skiing every couple days) but we'll definitely be back on the road come spring. Had 3 breakdowns this past year and used a mobile tech for one of them and got towed to small town mechanic for the other two.
