I sold our first TT with T-125's still going strong after 10 years, so it was a no brainer to put two new ones on our new to us TT. You get what you pay for and I initially had battery issues before the finding Trojans. Now for me tere is no other kind. You get what you pay for and the less expensive deep cycles, just do not have as many cycles as the Trojans. Great Battery and I expect 10 years out of these or more. I also installed the Trimetric Battery meter and a charge wizard module to smarten up the dumb TT charger.
We dry camp as much as FHU. Installed 428 watts solar and now they get full charges. I wish I went the solar route sooner. Maintence is simple, my typicaly routine is before I pull out of the driveway, is to check Batts, propane, tires air pressure and after a dry camping trip I check the batts as thats when it will boil off some electrolyte.
