Given this hypothetical I am hoping to get response on estimations of fuel costs. Looking at two year trip where I will stay in locations anywhere from two to 7 months. Starting in Miss. for two months then pennsylvania for 7 mo. then Palm springs, Ca and San diego for 2 months each. Then summer in Lake taho,Reno area for 6 months then Las Vagas for winter of 4 months. Which of the following choicesgwould have a lower overall fuel cost since I am staying in one location for months at a time. A 32 ft. 10 year old class A gas, towing small car for everyday use, or a 32 ft. 5th wheel towed by 3/4 ton 2500 series gas pickup and using that for everyday use. Would one be significantly more fuel cost then the other?
