Before I retired we had a 1 ton van at my work place with a 454 chevy and drove it for 500,000 miles without major engine work. I bought a 1986 Pace Arrow with a chevy 454 and drove it for 17 years, gave it to my son with 122,000 miles and he has it to this day, no major engine work. I now have a 2004 Scottsdale by Newmar with Workhorse chassis , 496 chevy and 65,000 miles and no major engine work. I am a long time Ford guy however because of my past experiences with chevy I chose to stay with them when selecting an RV. Like others have stated floor plan is still a high priority also RV Company, some are better built.
2004 Newmar/Scottsdale, W22, Toad/2000 Jeep Cherokee Classic 4X4 Auto Trans, US Gear Brake System, Blue OX Tow Bar, Garmin 1450 MT GPS. RVing Since 1989. Life Is Good!!!
