That's a vg point if the nights are cool and you need to run the heat , that's experience for ya .:W
If you are driving everyday you should be ok but I would pump it up to a larger battery just because it makes better sense.
If you choose to do so, you have a few options to carry a second battery on your rig , in the wheel well or a Tork-lift hidden battery box under the truck.
( if you have to for an hour, run the genny , at least you have that option, loud or not ) The Lance 8 ga wire with driving day to day works well for me .
The fridge will draw about .50-.75 amps while running on gas. Not much you can do about it.
My gas detectors use about 1 to 1.5 amps , I pulled the fuse and use portable detectors in place of it.
My tv and radio has a .50 amp draw while sitting there doing nothing because they are hot wired into the system to run the clock and memory.
I installed a toggle switch to kill any and all power going to them.
The only draw I have is my fridge while running on gas .
I used to have solar and now I don't. I do not miss it because I don't have the need for it with my camping style. I do have a genny in case I run into bad weather but hardly ever have the need to use it . I run two DEKA grp 31 AGM batts.
