Advice on deep cycle setup?

Yep let the alternator do the in-flight duty then connect to the house PV system to let the battery charge on weekends. If your home system was large enough you could even rig up a system to charge the battery at 14.4 volts during the week. 14.4 volts for daily 8 hour stints would not harm an AGM battery. Being after sundown the charger would be a DC to DC battery powered recharger.

My setup is similar. I travel with a 14' TT(cabin) and an 18' van(daily driver). There are two solar power systems which are described in detail in my profile. My main power center is the van which collects power and brings it back to the TT. The solar does the heavy lifting and the alternator is mere supplemental.

There is a 6ga charge line run through a SurePower 1315 bidirectional voltage sensing solenoid relay to/from the auxiliary 270AH bank. This allows charging of both battery banks in the van from either/both of the alternator/solar. In addition, when towing, both the TT and van solar systems cooperate to charge all three battery banks.

I can plug the 120VAC, TT power cable into the inverter in the van when at camp.

My setup is primarily electric with appliances chosen to complement the 1000W inverter:

* 800W induction hot plate. This has power settings 1-7 and the power draw varies from 300-800W.

* 950W Panasonic inverter microwave. This has 10 power settings where I can use powers 1-6 and stay under 1000W.

* 650W Mr Coffee 4-cup. This runs flat out at 625W.

* 2 sizes of crock pots which run 100-275W.

* 65W Satellite system and LED TV.

* 5000BTU AC. 400-700W. I did run this full blast for 4.5hrs recently on battery/solar only. It used 2KWh giving an average 444W draw. This was actually a battery capacity test of the 7 year old AGMs. I believe they passed the test.

120VAC genny/shore power required:

* 1300W toaster oven.

* 50A charger. The magnum in the van is an inverter/charger 1000W/50A

* 45A charger. The converter in the TT.
