Test drove Gtown 360xl last weekend

The coach rode and handeled well but I noticed that the tach was reading 200 rpm higher than my 11 378 at 60mph. The salesman told me that the axle ratio was higher because we were on a 24000 pound chassis. I was concerned that the higher ratio was going to cause lower mpg. The coach was made a lot heavier with its ceramic tile floor and residential refer.The DW did'nt like having the TV on the kitchen counter so I guess we will have to stay with our hard to beat 378 for a while yet.

Both the 24,000 and the 26,000 lb chassis have the same rear axle ration. 6.17
See attachment.
Maybe you were in tow haul mode? That would increase rpms

Remember the instrumentation may not be the most accurate device to judge your engine speed...........after all, it's only a gauge.

200 RPM is nothing to really get upset about. When everything is said and done, does your mileage appear to be within reason?

My 378 is on the 22000 chassis and turns 2100 rpm at 60. The 360 on the 24000 chassis was 2300 at the same speed .No Iggy, it was not in tow-haul.Mabey it wouldn't affect your mileage but I still would bet on the 22. I think the reason for going to that larger chassis is because these larger gas coaches are right on the borderline of being overloaded.
