I was surprised at the number of DP's that I tested that were greater than 20 secs to go from 40-60 mph.

That shouldn't suprise you. While many DP have high horsepower ratings, they also are very heavy. It is due to the weight that they have the diesel engines as a gas engine would simply be inadequate.

Acceleration/hill climbing is simply a function of the power to weight relationship with gearing thrown in as a modifiying factor. Good power to weight ratios exist in all types and sized of vehicles. The opposite is also true!

Yes your right. Even with shorter lighter DPs these times were much higher. Test drove a 34 ft Bounder 40 - 60 was 22 secs. They seem to put smaller engs in the shorter, lighter DP chassis, where as the gas chassis have the same eng. A 32 foot workhorse chassis motor home has the same 340 hp eng as a 38 ft MH. The conclusion that I have come to is that if you want a 30- 34 ft MH and want the good performance for hill climbing a gas chassis is better.
