Lots depends on the depth of your pockets for sure! Here's my cooking evolution. Cooked out of the back of my Chevy 1500 (had a topper on the back). Bought a 7x16 v-nose trailer and did it up the way I wanted (no facilities). Got into a bit of trailer trouble and moved up to a Chevy 2500 diesel truck (still with a topper on the back). Cooked this way until 2009 when the pellet Jambo was ready, went back to cooking out of the back of the truck and hauling the cooker behind. LOVED the fuel savings! HATED setup work and time it took. Got lucky and won a GC and down payment on a Sprinter Class B RV. It was new, but 2-1/2 years old on the lot, so got 1/3 off the top of retail price. First contest with it was Ashland, MS in the spring of 2009. Having facilities and ready to use kitchen and bed was phenominal! Better than that, I got 4-5 miles more per gallon with the Sprinter than with the 2500. 550 actual travel miles to a tank (26.5 gal.) of fuel. Since I'm a solo female cook, there's another big advantage to travelling this way. If I need to find a Walmart to sleep, all I have to do is park, lock and sleep. I'd love to have a bigger RV (Winnebago Trend is calling my name), but this one has been a peach!
