I think a lot is give and take and depends on the level of the coach and the upgrades from year to year. Our 1993 was purchased with many upgrades such as corian counter tops, upgraded cabinets, solid flooring,full queen mattress and other little touches that has made it nice but more important has helped the coach last. The chassis being a spartan has also taken us many carefree miles. We have 4 wheel disk brakes our cummins was the newest out with 230 hp. and allison MD3060. The big difference is certainly not having slides which today for most would be a deal breaker. The shape of our coach helps with aerodynamics but I am sure no one would think it is in vogue today. If our coach was new it would likely be around 340 HP. so once again upgrades and chassis has been significant over the years.
