So after talking to a local heavy duty tow truck company the price tag is 620$ per hour to come get the R/V off the property.

I know in my projects, there are times where I will have 5-8 trucks/vans in driveway on street during certain phases. 

I'll have the truck here for you and I'll help you guys move.

You’ll check if their work is good, if they look like they know what they’re doing, if they have a late-model pickup truck—things that indicate they are competent and professional.When a motivated seller does a Google search, they’re no different.

Sadly, communication consists of "if you don't like it, hitch your trailer to your truck and get out".  

Then it could be quite different and just make the gate motorize, move in base and rent to trucks ( yes i get way over simplified), going to look for more resources on that possible route as the required capital would be drastically less for possibly a better ROI. 

Or in the case of appliances, who meets the truck, checks the products and signs for them?

I really should have had someone with a bucket truck or a couple younger guys.

You might see investors / main contractors hauling debre away in their pickup trucks late evenings and sunday... 

Very few succeed with this model and those who do are the contractor types who are driving around in their work truck putting out fires all day.
