Since you are just starting out, I recommend buying a 1/2 ton p/u at a minimum. Back in the day we (and probably most folks here) started with a small/light trailer but bought a longer, heavier TT within 5 years. That made our tough F-150 way under-powered so we upgraded to the 3/4 ton diesel in my signature...a night & day difference.
Be prepared for fuel sticker shock: when towing my 1/2 ton avg'd 8-9 mpg and 35 mph up our mountain passes; my current 3/4 ton diesel tows at 10-11 mpg and 60 mph up the same mountain.
After a few TT years you will finally find and purchase the "set-up" that makes you happy.
