Is it toward the top front?
Yes. It is the top front bolt hole that is not used on that passenger side bell crank.
In general, from my understanding of the wandering problem with the P30 chassis, it can be related to one or more of the following: (not that any particular one applies to your problem):
1. Worn out steering and suspension components, shocks, etc
2. Shop alignment not done correct for a P30 motorhome chassis
3. Design of the motorhome places too much weight on one corner or side.
4. Motorhome is way overloaded (sometimes the factory builds them with virtually no ability to carry anything without being severly overloaded.)
5. The overall length of the motorhome is too long for its wheelbase. (Too much motorhome hanging off behind the rear wheels.) When this ratio gets below maybe roughly 55 percent they tend to wander and be difficult to handle -- especially in some conditions such as cross winds. (the wheels on a 100 foot long motorhome should be at least 55 feet apart -- for a simple example)
There are some reports of people having to constantly steer their rig such that they are exhauste at the end of the day. Some posters think maybe these drivers are oversteering constantly. They say to just relax a bit. I personally find that idea hard to believe but it gets mentioned quite often and must be based in some knowledge.
These list will give you a frame of reference as you work through the problem and maybe look for some additional help.
One thing you might do is load up the rig as you travel and find someplace to weigh the rig. There are lots of truck scales all over the place capable of weighing your front and rear axle. You will get a printout on the ticket for front axle, rear axle, and the total weight of both. Cost would be maybe $10. You don't need a certified ticket which would cost a little more.
Better though is a shop that can do individual wheel weights. They will give you four individual weighings. left front, right front, left rear, and right rear. Cost maybe $120 (california price).
Note that it will be a rare motorhome with balanced weight on all four wheels. It just does not happen nor is it important so long as it is not severely out of balance on one corner.
I would have to add that the front wheels being four feet on center is no help. Adding a rear trac bar to help the tail waging the dog. A P30 was ment to be a potato chip delivery truck not a rv.
