On the topic of pickup verses car and trailer, if you only need to move bulky items occasionally, a car and trailer wins hands down.
I recently completed a quick 1000 Km road trip with my i30 (1.8 litre, Auto) pulling an 8' x 5' box trailer (just a bit wider than the car).
The i30 has a lifetime average of 39 MPG at present, the FE for the two fills while towing only dropped to 30 MPG. That's a drop of 9 MPG, but only for 1000 Km of the 18000 Km I've put on the car since purchase last year.
Keep in mind, I can fit a fair bit in the i30 hatchback with the rear seats folded flat before having to use that trailer. I've made the same road trip with the car stuffed to the gills and still got 38 MPG.
