But a hatch on the side of the trailer for the cord to pass through. Those marine twist lock cables look cool.. But they are very expensive and pointless. Every campground is going to have a standard outlet on either a 15 or 20 amp breaker a standard 30 amp RV and or a 50 plug.. If you use a twist lock you will also need an adapter. So you will still be plugging your trailer into the outlet with the standard plug.. Just matters if you want your cord to cost 50 bucks or 200 bucks. You want your adapters to be 8 bucks or 30?. A smaller trailer shouldn't need 50 amps, I wouldn't do less then 30 amps though. Like us our trailer has a microwave and Roof AC, I can run both on 30 but I would not be able to on a 20amp.. Even if you don't plan on having big stuff.. What if you end up with a coffe pot and a boot drying.. I Also carry both of those with us camping. They are very small but still use a fair amount of power..
Gotta go with 8ball on this one. When doing our CT conversion I went with a Marinco 30 amp inlet, the twist lock marine type. It was expensive, and the shore power pigtail adapter required to convert to a standard three prong plug even more so. All in all it was pointless and expensive, but then again, at that time I didn't know better and there weren't many (or any) such conversations in this forum. There is a lot more shared knowledge here than there was when I started my build just two years ago. Take advantage of it.
Also, I agree with the consensus, go with a 30 amp inlet. Better to have 30 amp access when you don't need it than to not have it when you do need it... i.e., if some is good and more is better, then too much is just enough.
Also, 8ball's recommendation of putting a simple hatch in the side of your CT has a lot of merit. I have done both (see photos below) and were I to do it all over again I think I might just go with the simple hatch and keep all connections inside the CT by running a cord through the hatch. That hatch cost me $5 at Camping World. The Marinco plug-in penetration/hook-up and the required Marinco pig tail to convert cost just about $100. $5 vs. $100, and both work equally well? Not to difficult to figure out.
