My travel trailer is only 23 feet long and is designed for a 30 Amp hookup. The last time I went camping tough, the A/C wouldn't turn on. Everything else worked with 30 Amp hookup but no A/C. Luckily there was a 50 Amp switch, so I switched to the 50 Amp connection and the A/C fired right up. Has this happened to anyone else? Do I need to reserve only 50 Amp sites in the future? They are more expensive, so that would be disappointing, and I can't imaging that all of those larger RVs are going without A/C in those 30 Amp sites. I've only been RVing for 2 years, so I'm still a little new at this. Thanks in advance for any info you can provide!
