Sorry to beat a dead horse here, but please be extremely cautious about removing tag axles. On the 4905, since it was an option, you can probably get away with it.
HOWEVER, I *STRONGLY* suggest (again
) that you weigh your bus first to make sure your weight will not overload the axles or tires.
For any other coach, PLEASE be very careful. Some have said that their conversion will not weigh as much as a loaded passenger bus. I really question how often that happens and if they have actually weighed their conversion. It is easy to fall into the trap of estimating the weight and I will guarantee you that your estimate will be low. Almost everyone I know that has had their conversion weighed, has been quite surprised at how heavy they are.
Again repeating myself from previous posts, the total weight is only a small part of the issue. The real issue is the weight on each axle and EACH tire!
Also repeating, if you modify your bus by removing a tag (unless it was an option) you expose yourself to some HUGE liability issues since you have reduced your braking capacity (plus the possible tire overload condition).
Just playing "devils advocate" to those who casually recommend removing tag axles.
