We don't boon dock but sometimes overnight at a rest area or truck stop w/o shore power. This is 200 AH equivalent to two 6v batts. and nearly as heavy (130lbs). Had to use a portable engine hoist to get it in the compartment. Since it is a sealed AGM battery I didn't need the bulky vented battery box and gained much storage space in the forward compartment. My TV has a huge alternator and will charge it up just fine in between stops. I do carry a gen just in case we stay longer. I have only had it for two months but so far I am very pleased with the set up.
170 ah , 12v LIFEPO4, from bigbattery.com is now $899. I would offer that as a reasonable alternative to the Renogy AGM above. Gain 70 AH and save 100 lbs with probably 2x lifespan at an added cost of $500.
