Hi, I'm going to be picking up 2 new 6v deep cycles to replace a pair of old group 27's for my camper battery bank. Charging will be mainly solar, 230watt panel with morningstar 15mppt controller. From the brands I have available locally I've narrowed the choice down to Crown CR-235 vs Trojan T-105 with the Crown's being about $10 cheaper per battery.
It seems that Trojan has the better reputation and brand recognition, but the Crown's are rated at 10 Ah more and are marginally cheaper. Which would you choose?
Thx in advance
Glad someone beat me to it re the frontal area. That makes all the difference in the world between 2100# of boat and 2100# of travel trailer. I am getting the feeling that the OP is looking for support in this decision and not finding it.
OP, please understand that folks on the forum have been around a long time, have seen or heard most and are only offering suggestions based on their knowledge. We may not be perfect, but usually pretty much right on with the opinions. If you have already made up your mind to go with this combo, we all wish you the best and safest travels. If you're after solid advice, please take it in the spirit it's intended.

I wouldn't push it too much, but you should be well within all your specs with this trailer. I think you'll find the minivan makes a very good tow vehicle.
The problem with wooded and shady is the panel(s)do not produce enough voltage to actually charge the battery. I made a mistake when I purchased a 66 cell 185W high voltage panel on Ebay meant for a grid tie system which will put out no load 70+V. This required a MPPT controller that will convert that high voltage into usable current. What this means is that I get usable current from sun up to sun down and with shade. I have seen 17V from a full moon and typically 36V in a shaded camp site. The Morningstar SunSaver MPPT controller is about as bullet proof as you can make a solar controller.
Ditto here, I went with high voltage grid tie panel for the same reason plus watt for watt they seem to be cheaper. We use that same sunsaver mppt controller and a 230 watt high voltage panel and in treed, cloudy, even rainy conditions its still putting out 25-30 amp hrs per day at 30+ volts. More than enough to maintain 2 batteries IMO. The only other issue is snow, you'll get zero charge if the panels are buried :)
