I will also throw my .02 in... there are a bunch of variables here whereas it MIGHT be ok EXCEPT your first line is a deal breaker... being inexperienced you don't want to put yourself in a situation where you HAVE to know what to do.... or else.... unless you are SURE you'll know what to do.... Now that said... if I knew the route was all secondary road, light traffic, minimal hills where I could SAFELY run 35 mph or less as needed with the hazards on I'm confident I could safely get the move made.... Insurance is always brought up on these questions... of course it would pay.... If doing something stupid was a no pay kinda thing 99% of claims would be unpaid.
sooooo while the above advice to find a bigger truck ABSOLUTELY IS the best advice, if the route is an easy one and you have a much more experienced driver it wouldn't be absolutely impossible....
Example, my jeep has either a 1000 or 2000 lb tow rating and I have moved my 10,000 lb boat all over the yard and onced moved a 7000 lb boat 2 miles down my country road to a friend's house with it.... all at 5-15 mph and never for a second was anyone in any danger....
Higher speed, steep hills, heavy traffic, etc would all make for a VERY bad day FAST.
Normally I tow my boat with a crew cab diesel dually
