Looks like our twin bed conversion will not start until after the new year. The shop has too much scheduled work this time of year.

Lithiums would be nice but they are way outside of our budget.

I read somewhere someone stating Trojan AGMs need to be vented. Is that true?

Technically, (especially if you ask the battery makers) ALL lead acid batteries should be vented. Since the only lead based batteries that I use are Lifeline AGMs, my comments will relate to them specifically.

All Lifeline AGMs recombined any gasses created during the charging process back into the glass mat material. In the unlikely scenario of severe over charging (above 15.5VDC at 77 deg. F) or thermal runaway, the one way safety vent in each Lifeline will open and expel excess hydrogen sulfide gas.

This also decreases the amount of moisture within the battery, changing the chemical makeup and essentially ruining the battery.

In 15 years of Lifeline installs, I have never seen this happen, except in controlled lab conditions. I have also never vented any of my Lifeline installations.

Again, I can't address the operating characteristics of any other AGM brand.
