.BTW - I don't understand why manufacturers are still building larger RVs with 30A service.

Up until 2005, the NEC only required 5% of a CG/RV park to have 50 amp sites. Then in 2002, it was changed to 20%. In 2017, it was increased to 40% of CGs required to have 50 amp sites. Finding 50 amp sites can be very difficult. Some CGs and RV parks may have built above the min. code requirements such as casinos and some gov't facilities for ex.

Unless we had a larger RV, I'm quite happy with 30 amps. There's been a few times when one AC unit hasn't been quite enough but wouldn't want 50 amps and have to plug into 30 amp pedestals with adapters most of the time. I see 50 amp RVs all the time using 30 amp pedestals including very expensive large MHs. One thing for sure, you won't find dealers or RV manufacturers telling potential buyers that 50 amps may be hard to find.

COST, Plain and simple. Just like when Car dealers advertise a CHEAP entry level Auto at the cannot believe the price. They order those cars with NO AC systems. Drops the cost and then they attempt to get you to upgrade to the higher price car. This is not Bait and switch. They DO HAVE the car as advertised, just not with the normal required equipment. Look at various posts on this forum where people have large RV's that have both 30 and 50 amp. The ones with 50 amp and over 28 foot long and have 1 AC unit complain that the unit cannot keep the unit cold when it is hot outside. The Dealer ordered that unit with 1 AC to keep the cost lower. Units with 30 amp service with 1 AC are built and sold to keep that advertised price a few thousands dollars less than the competition. Manufacturers do NOT dictate this. It is the Local dealers that drive the practice. Doug
