Chevrolet C/K TrucksChevrolet trucks are some of the most popular vehicles in the United States — they've been around, in one form or another, for over 100 years. The C and K series of Chevy trucks are considered some of the most desirable Chevy trucks, with a classic design that's still popular today at car shows and drag race events, and in some cases, they're still used as daily drivers.Technically, production of the C/K trucks began in the late 1960s and carried over into the early 1970s. Then, in 1973, the C/K pickups were redesigned and the era of the Square Body began. Available from 1973 to 1987, the Square Body was GM's longest-running production truck. A truck that lasts that long means lots of spare parts for repairs and many different versions to choose from.Over the years, multiple cab configurations, bed lengths, and available powertrains have been available, so you'll be spoiled for choice. Single-cab, short-bed C10s are desirable for show vehicles, so they're a bit pricier than the average farm truck. However, variants like the long-bed C30 would be an excellent option for towing hay, moving tools, and generally doing farm work.Chevrolet El CaminoIf you don't care about four-wheel drive, towing capability, or boxy looks, an El Camino can definitely do some work around the farm. Just like any good truck should, it's got a functioning bed, but an El Camino has the added benefit of a lower load height than most trucks — making it much easier to load small items in a hurry.In the 1970s, there were three generations of El Camino. The first and second-gen El Caminos came earlier, but the third generation El Camino was made from 1968 to 1972, the fourth generation from 1973 to 1977, and the fifth (and final) generation of El Camino was made from 1978 until 1987. As was the case with the Chevrolet C/K trucks, the El Camino's long production run meant that lots of these trucks were produced — which should make finding one relatively easy. And, like the Chevy C/K trucks, the El Camino shares many parts with several different GM vehicles, so maintaining one shouldn't be too difficult.
