Is it bad to trickle charge continuously?

[Johnynorthland]

I’m just curious is there any harm in keeping my lead acid chassis battery trickle charging when I’m plugged into GG for 2 months or more? Should I pop the caps on the battery so it vents better?

As long as you have a good trickle charger. No harm. Leave the caps on.

Most vehicle manufacturers now add technology to minimize parasite power drains issues.

Personally, I would have a multimeter and check tje change periodically. Then plan to start the chassis engine once a month and let it run for an hour.

We leave the Rv and garden tractor batteries on a Battery Tender Junior while away for 5 or 6 months and never had a problem. My 6 month guarantee tractor battery is on it's 4 season. Some like a Noco Genius brand but I will keep mine till they die.
These "tenders" have a chip that just puts enough power to keep the batteries at 100%. Some "trickle" chargers put a consistent amount of power into the battery which may be to much or not enough.

A trickle charger always charges, whether it needs it or not. A smart charger or battery tender varies the charge depending upon need. For the last 7 years we've just plugged our camper in and let the inverter monitor and charge as appropriate.

What is a GG?

If you are using the converter in your camper to trickle charge, be careful. Check to see if it is a smart charge type. My 2008 BHS wasn't, put 13.6 volts into the batteries constantly. Almost wrecked my new 6 volt golf cart batteries I had installed. Got a new converter from Best converter that will only give he batteries what they need, 14.7 V when they are down, drops to 13.7 V to top them up and drops to 13.2 V float. Works great.

A battery tender or smart charger external to the camper would be fine

Left mine on Battery Tender for 4+ years 24/7 while in storage, no problems at all. Caps on, just check water level every couple of months.

I leave our TT plugged in year round.

I've used Schumacher brand battery maintainers on all my other items that need off-season battery tending. Used on snowmobiles, boats, motorcycles, cars and even my old Cessna 172 airplane with a 12 Volt electrical system.
