As Pat pointed out if everything on a vehicle of any kind was the very finest it would take all the gold in Fort Knox, if there's any left, to buy it! I own a 17 foot Casita travel trailer and battery types and care are a constant topic on trailer groups too. Most people end up replacing the standard wet cel battery with another of the same type. The extra cost does not warrant the better agm battery for most people. But those that do get them buy expensive shore power converters to keep them charged roperly. Both can easily cost $400 then some opt for two batteries. There is no perfect battery!
Let's get back to tires or maybe fuel lines :=}
