Charging sealed gel cell batteries from an alternator

I am installing a 120 volt house power AC system in my conversion van and would like some feed back from others here who may have or may know what I am attempting to do. I have 2 Eaton VRLA sealed gel batteries that will be connected in parallel and are 75AH ea with a float voltage of 13.5-13.8 volts. The total connected continuous load will be close to 300-400 watts, (while I am camping). My plan is to install a 2000watt pure sine inverter as I want to have the capacity to run short term larger loads if needed. My intention is to install a parallel charging system supplied from the alternator on my 1996 Chevy conversion van. This will be wired thru a battery isolator or voltage sensing relay so as not to drain my start battery while the inverter is on and the van shut off. I will mount the battery tray under and outside of the van welded to the frame of the van. This is to keep air circulating around the batteries while I am driving down the road. This will also allow me to mount my inverter less than 3 feet from the batteries. The charging circuit cables for my house batteries will be about 10 feet long each and connected in parallel to the start battery. So here are my questions and concerns.
1.) I will be driving cross country for extended periods of time will this charging system damage my gel batteries?
2.) Will #2 fine strand welding cable be sufficient for the charging circuit, or is this overkill?
3.) What size fuse is needed for the charging circuit?
4.) What size fuse is needed for the house circuit to the inverter from the batteries?
5.) What would be a good inverter for this kind of application? I would like over voltage and under voltage protection.
6.) Where is a good place to source this kind of equipment?
7.) Thanx in advance for sharing your knowledge and experiences!!
