Coincidence?

The old boy was just fine, 1999 Georgie By pursuit, 25', 454. Fired him to bring back from beach after 2 months, and the dash lights, gas gauge, charging meter, and speedometer all are not working!! Could they all be on same circuit or fuse?
While I'm at it, Long standing discussion with neighbors, TIRE PRESSURE. My Georgie Boy says on the door tag and LT michelin tire to be at 80 pounds. 2 friends say that is not right. I say then why did the factory and Michelin say 80 when they meant 60, Bus is 12,000.

If you have the same brand/model/size of tires then the factory sticker is correct for the rig loaded to it's maximum, otherwise it's wrong and the only way to know is to have the rig weighed ready to travel, then consult the tire manufacturers charts for the correct pressure.
Your friends are not correct UNLESS that's what they have done for their rigs and they're exactly the same and loaded the same as yours.
Quote:
From Michelin, their quick summation of two pages of their Recreational Vehicle Tire Guide:
"The amount of air pressure you need to use depends on the weight of your full-loaded vehicle. So, you cannot determine your correct air pressure unless you know your vehicle's actual weights"
"A tire that is overinflated for the load that it is carrying will also contribute to a harsh ride, uneven tire wear, and will be more susceptible to impact damage."


From Toyo's Recreational Tire Vehicle Guide
"The amount of air pressure in a tire determines the load that can be carried safely. Every Toyo Tire will have the maximum load and inflation molded in the sidewall of the tire. THIS LOAD AND INFLATION RATIO SHOULD NEVER BE EXCEEDED SINCE THIS CAN CAUSE HANDLING PROBLEMS, IRREGULAR WEAR, AND COMPONENT FAILURE. The proper amount if air pressure is always determined by the weight of your RV fully loaded. This weight takes into account all liquids, supplies, and passengers. Tires on RV applications are subject to a variety of more severs conditions when compared to automobiles or trucks. Because of many chassis and optional equipment differences, it is possible for an RV to be within its Gross Vehicle Weight Rating (GVWR), but overloaded when taking into consideration the weight if each wheel position. The only way by which you can know the safe load and inflation pressure for your RV is to know the actual weight of each wheel position under actual loaded conditions. Underinflation of a tire can cause poor handling, irregular wear, and decreased fuel economy. It also causes extreme heat build-up within the components of the tire, which can lead to failure. Overinflation of the tire causes deformation of the contact patch resulting in crowning of the center tread. This causes handling problems such as reduced traction, irregular wear, and an increased chance for impact damage."

Firestone says:
"Find the RECOMMENDED Inflation Pressure
Always determine correct tire inflation pressure based on actual loads on the tires. Use the tiremakers’ recommendations (which you will find in load and inflation tables). Never use inflation pressures lower than those printed on the vehicle placard.
All tires on both ends of an axle must have the same inflation pressure. If the load on each axle end is so different that different inflation pressures are recommended, use the higher pressure on both ends – or – redistribute load so that the same inflation pressure is recommended for both axle ends."

May not be on the same fuse but I would bet they are on the same ground. Check for the dashboard ground

X3. When you have several unrelated but simultaneous electrical symptoms, its a system problem. Either alternator or grounding. Beaches are tough on electrical stuff.
