Trojan vs interstate 6 volt

So I have been doing a bunch of research regarding which of these 2 batteries are better. I found the Trojan T-105 on sale locally for the same price of the interstate GC2-XHD. The interstate specs are a little better than the Trojans.
My TT currently has US batteries (6 Volts), and I am not at all happy with them. As soon as it gets cooler out they fall flat on their faces very quickly. We dry camp the bulk of the time, and we even upgraded to their green top, but they just don't work well enough for us. Our previous TT had 2 Interstate 6 volts and we could easily get about 5 days dry camping, using our generator a couple hours a day for topping off with no solar. Our new TT has a 160W solar set up and we can't even get two days. Our selling dealer did find some electrical issues. They replaced 3 or 4 overhead light assemblies, and adjusted the furnace. We are also installing LED lighting through-out. So my electrical drain issue is resolved but the colder temps are still a issue. From what i have read people are getting around 7ish years with their Trojans. I have always had very good luck with Interstate batteries. What are people's experience with these 2.

Having never used Interstates, I can't comment on them but I have always used Trojans - in both RV and marine applications. I installed 2 T105's in 2008 - 7 years ago and they are still performing well and would highly recommend them.

Thanks for the reply, how far do you let your batteries drain down before a re-charge. Guess what I am asking is do they hold up to abuse such as bringing the charge down to say 60 or so % every so often, and how do they hold up in colder temps?

Costco 6 volt golf cart batteries. $89.00 each 3 years ago. I'm told they are made by Johnson Controls?.

The RV is kept and stored in the Fraser Valley year round - including the winter. As you know, our winters are generally mild but we do get some stretches of below freezing temps. The batteries remain outside during the winter and I make sure that they are charged up

We also do a fair amount of dry camping and in conjunction with our solar panel (85W) we are able to stay out for several days or longer if the sun is shining. I'm not sure about how low their charge gets before bringing them back up as I don't monitor them that accurately (but I should, I know - )

We're very happy with their performance.

Thanks for the replies, I just made up my mind, and I am going with the Trojan line, I really like that they make their own batteries. All the reviews I have read say nothing but positive, guess I just wanted a couple extra experienced opinions. I will pick them up in a couple of weeks. PS for us Canadian folk Lordco has them on sale.
