Yes a little more info, 'full time, lots of travelling or stationary most of the time. Single or family in the RV, needs work station or something else.
My suggestion would be to start with a used unit, new unit kinks should be worked out, How much do you want to spend? If used and you decide that you don't like the life style, not as much money invested.
Get or decide on a particular RV first, then look for a tow vehicle. Go at least size bigger on the tow vehicle than you would need for that trailer. i.e. if a 150/1500 is adequate to tow the trailer, look at 250/2500 or even 350/3500 series that will make for a more relaxed tow, and may accommodate your next trailer when you decide your original choice is TOO small.
