Agree with all the suggestions of staying near the dealer until you have used all equipment and are satisfied.
My sister and brother-in-law had purchased a motor home ( huge unit). They bought from out of State and paid to have it delivered. All promises were made.
Two weeks later on their first trip the gone board generator did not work, although it fired up at the drop off and signing. It was then fired up again before their trip.
Two weeks later.....nope.
They had a he'll of a time getting the dealer to comply with finding the problem and fixing it.
Because the dealer was out of State they ended up paying out of pocket and then threatening the dealer to get any money back.
End result, they lost $'s on the deal and have said they will never do that again.
Stay in the area :)
