We have four 6 volt Costco batteries, 300 watts of solar, 1200 watt inverter and 4000 watt Onan generator. Can run everything (Dish receiver, 2 flat screens, all 12 volt applications) without ever using generator so long as there is sun. Coffee maker, microwave, or A/C require generator. Boondocking time limited to grey water capacity.

Your should NEVER run anything with resistive heat on generator or solar...

Wiring

My Montana did come with solar prep but that's all. I installed a Onan 5500 and had four Lifeline 6V AGM's. Looking to add more Ah's I'm switching to Lithium and increasing my solar over what I had previously installed. With adding that much solar you may want to review all the wiring, components and fuses and make sure everything is up the task, besides the batteries and solar panels. I would run that much power through the 10g factory wires.

With the different charging parameters of lithium batteries you need make sure the solar charge controller is designed for it also.

Plenty of videos on YouTube.

I considered AGMs but my concern is weight, and LFP fixes that. At a price, steep too. The problem we have is the CCC numbers. with all the goodies on boards we have only about 2100 lbs of CCC left for our stuff, food etc. This why the LFP option works for us. YMMV as they say.

Engineering friend of mine says the pin weight should not exceed 25% of the total OEM trailer axle weight rating. So we should be good. we are also considering an air-ride pin box.
That Air Ride pin box will smooth out the ride for sure. I have one. One of the best options I have added for sure. Damps down chucking but does not eliminate it.

With all the weight being discussed, between the generator and all those batteries, I wouldnít be as worried about the axles as I would be worried about the frame coming apart where it connects from the upper frame to the vertical frame at the propane compartments. That is a weak area of these rigs and you likely will eventually have a major frame failure. Beefing up those areas of the frame might help avoid structural failure.

That frame issue is the original 'frame flex' from back in 2006-2010

I know of a 2015 that had the frame flex so this is not just a 2006-2010 issue.

A lot of frame flex now-a-days seems to be around the front slides. The old ones were where the upper frame attaches to the vertical frame going down to the main I-beam under the trailer. The one I described seems to me to be way more dangerous than the new stuff since the whole thing could come apart rather than just a section of the wall by a slide out. But yes there are the 'old' frame flex issues now but I think much less frequently.
