Well, ive owned a few big RV's, and currently own an old MCI Coach converted to RV. If it needs a tow, a big huge diesel semi tractor tow truck will be called. Those tow trucks can cost from $250K to as much as $500K. They have large onboard air compressors, tools and tire equipment, heavy winches and recovery gear, fire fighting equipment, and someone on call 24/7/365. They also must be maintained to comply with DOT, drivers must pass DOT, mega buck insurance because of HUGE billboards put up by attorneys wanting to SUE Semi Trucks, etc... I insured a large wrecker myself once. Once. Its a lot of money.Really?
After putting out around $80K - $120K for vessels (if you have only two and they're small), equip them with the necessary electronics, dewatering pumps, liftbags and compressors, safety and firefighting equipment, maintain those vessels that are in use daily, fuel those vessels daily, insure your operation, insure those vessels, man those vessels around the clock (three shifts X 2), insure your employees, pay for a facility from which to operate and hire lawyers to chase down unpaid invoices, let's see what you would charge.
Keep in mind, the weekends might be busy (MIGHT be) but mid week not nearly as much and likely the business is seasonal. Oh yeah, somewhere in there you need to afford to live in some of the most expensive areas in the country.
Good luck.
And I can be picked up and hauled anywhere for between $125 to $250 an hour or $3-5 a mile. Sorry, no one is worth $9500 an hour. Hell, I think the guys with the Snap On trucks have over $500K wrapped up in their equipment and merchandize, and they could only dream to make that kind of money.
