I have looked at several different manufacturers and would love to hear anyone's experience with any.
There is a bit more to it than that. Your trailer has 30 amp 110 volt AC service, your 30 amp converter charger is 12 volts DC. The fact that both are 30 amp is just happenstance.
Now, you may not find a good quality 3 stage converter at 30 amps, I believe most of them start with the lowest rateings at 45 amps.
If you do much dry camping, (no shore power) and use a generator, a bigger convertor charger that will charge at 14.2 volts will help recharge the batteries quicker, and require less generator time. If you do upgrade, make sure your wire size is adequite. It that regard, just because a wire size will carry 30 or 45 amps, does not mean it is adequite. If the wire run is very long, and you have a wire size that will just carry the amperage, the voltage drop will be very large, and you will not recharge those batteries very quick.
If the above conditions, (dry camping) do not apply, and if the 30 amp charge is adequite for your normal use, then no need to go bigger.
My Mh came with a 55 amp single stage- I will be upgradeing that to either 75 or 80 amp, 3 stage and makeing a big change on the wire size. The wire size as built is # 10, with a 40ft run to the front where switching takes place, from the back where the convertor is, and then back about 30 ft to the Bat compartment. At 45 amps, that translates to almost 2 volts of drop. The batteries then charge very slowly. I will be going to #4 cable, and cutting the run to about 15 ft. You probably don't have these long runs, but you see my point.
