thanks man
and your talking about the extra wheel thats inside like the lugage area?
Tag axles mounted ahead of the drive axle on the P8M-4905A coaches. This tag axle was apparently an option that could come with the coach when ordered by the customer. Notice the smaller wheel and rim size, basically what it does is it helps remove some load off the drive axel and I guess that would make the bus engine have less stress and wear.
this ?
