There is a lot od good information for the OP to digest. I have found that my F-150 E-boost is the perfect match for my 25 ft. Dutchmen trailer.
However, Just because if find it a delight, does not mean everyone would. My perfect match might be someone else's white knuckle adventure.
That is why I always tell first timers to Rent before you spend the big bucks.
We did and discover the 25 ft. was just right for us, however the 200 hp. tow vehicle was not going to do the job.
Renting is also the best way I know to check out the floor plan before you buy.
