Trailer towing hookup questions

12 miles to dirt track, 1 hour to drag strip, all 2 lane 45 and 55 speed limits no real hills just a few turns. trailer is 2 axle no brakes at this time but wanting to add, weight 1000 lbs and 3000lbs is heaviest load ill pull. my truck is a 1980 D150 /6 od833 short bed no power anything and im not thinking its got heavy duty nuff rear suspension to even consider but might could if upgraded right maybe. got a RV i plan to use when hole family gose with me but not wanting to feed that big monstrosity every time i wanta go play, am i crazy thinking my lil pick up could handle it???

I had a 81 D150 with the slant and od833, I got passed flat towing a jeep cj one time up a mountain 2 lane by a semi pulling a trailer.
The slant will not have any power, when that truck passed me, I told my wife, I should un-hook the jeep, and tow the truck up the hill.
