I test drove a 1990 Toyota Winnebago Warrior with a V6 today and left a deposit on it. I currently have a '78 Toyota Dolphin, (17ft) that I absolutely love... but its lack of power on the freeway or long inclines scares the ^#*@ out of me! I'm not sure the size or weight of the Warrior yet, I'm guessing it's probably about 22ft. Does the V6 engine offset the additional weight of the bigger camper? or will I be in the same boat essentially when it comes to no power on long inclines? I live at high altitude in a hilly/mountainous area. When I drove it today I could get it up to about 60 max on a long incline where the speed limit was 65. Is that about the max I could expect? What kind of mileage can I expect? (I average about 14-17 in the Dolphin). What else can anyone tell me about the differences I might expect between the two?
