I did some testing last weekend camping. After my 2 6v Trojans were fully charged I shut the shore power off and ran off the batteries and kept an eye on my voltage moniter.
Just the fridge running (I don't think the fan inside ever shuts off) and the parasitic draws from the CO detector, radio, and tv's the rig pulled 9-11 amps for the 5 hours I tested. (It got too hot and I had to turn on the AC, so back on with the shore power)

With my batteries having 220 ah and working with the 50% rule, I would only last about 10-12 hours and I didn't have any lights on.

The day before I traveled for about an hour and the fridge compressor was on for a good portion of that, then using the auto level the batteries were almost kaput. The levelers were having a hard time with little battery power ( I ran auto level 2 times)

That made my decision to put in solar. Two 6volts aren't enough. I love the residential fridge, it's a keeper. I'm needing solar to keep it going. 260watts isn't all that much, but I don't want to put a huge investment into this for the occasional 2 days I don't have power or a day stop over somewhere for a day.

If I need more ah's I'll get 2 more 6v's someday.

Tough call what to do about your 12v's...it's a shame to yank them and invest in 6v's. Plus it's tough getting 6v batteries in the bottom and top shelf of the battery compartment
Also I think 3 160watt panels might be too much for the pre wired 6ga Jayco put in. It also has a 30amp breaker pre installed too.

If you have deep pockets go nuts! My pockets got shallower after paying for my rig. Plus I have alligator arms to begin with.

Any solar gurus feel free to correct me on anything, or give some good advice.
EDIT... I meant Jayco's prewire is 8 gauge.

Thanks Klassic, you've got a lot of helpful info. In the end we bit the bullet and are having the dealer install the solar panels. They claim the 160 watt panels will serve our needs and at this point I'm going to assume that they are familiar with the wiring needs. It's going to cost us more, but with the trailer still being under warranty, I wanted them to do the work so they will have less of an opportunity to weasel out of any warranty repairs which might occur in the future. Regarding the expense, well I guess my kids can inherit it when I croak.

The dealer did recommend going 6v when the time comes to replace the batteries. I'm noticing a big variation in price. I assume this has to due with amp hours. More research needed I suppose.
