I'd suggest driving down to a local horse trail one Saturday afternoon and see what trucks and trailers are in the parking area.
We rode the Chickamagua battle field New Years Eve, there were 7 trucks with trailers, 5 fords, 1 Dodge, and one Government motors.
Two were f-350's, the others were 250's or 2500's....rarely, but on occasion do I notice a half ton.
So when you have time, go look and see if you see any half tons in the parking lot.
If it's flat maybe a half ton will work for you, but you'll be starting with a truck that's already at it's limit for pulling that much weight.
I went to the 350 to get well below the rated max. Frankly, the 350 doesn't know the trailer is behind it. If I don't look back, neither do I.
I think a 250 would be a better choice if you can make it work.
For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places.
