Cost of RV transport services

We are going to purchase a fifth wheel, in the 40 ft range, 2-3 axels. We plan to stay in it during working up and down the east coast. We will need to move it probably on an average of 3- 4 times a year and at an average of 800 miles each time. I see, or at least I think I am seeing that hiring someone to move it is going to run about $1.25 to $1.50 per mile. Am I close in assuming this? I think this will be cheaper then having to purchase a truck to haul the camper, because we will need a substantial truck suggestions? or advise? We are looking at a 2015 Rushmore Lincoln
