What will give you more bang for your buck, switching out all your incandescent bulbs to LEDs or switching the wet cell batteries to AGMs?

LED's. Similar size AGM vs wet cell will have about the same amp hour rating, but the AGM you can discharge to about 80% discharge, a flooded cell can be discharged to about 50%, based on safety of battery life for both. So a similar size battery with 100AH rating, you'll get 30% more AH. LED's are about 80% more efficient than halogen and incandescent bulbs. So those 10-20 watt halogen bulbs become 1.5-3 watt led bulbs. So you're trading off 30% extra battery capacity for 80% less draw by the lights.
This is looking at the lights only perspecrtive, it doesn't take into account extra 30% power the AGM will get you for running the fridge, furnace, or other 12v loads.

But I got seven years out of my Optima AGMs, and didn't have to build another vented battery compartment to place a second batt.

I don't use the trailer lights much. and I spend most of my waking hours out side. I have been using solar powered LED garden lights. Zero drain on my house batts. For me it's enough light. Use them inside and out.

If the majority of your usage is lighting, you're much better off with LEDs. If your lighting use is slight but you're running the furnace blower and a couple CPAP machines quite a bit, AGMs could conceivably be a better deal.

Or do both.

LED's then upgrade to the AGM's when the time comes.

LED, but AGM is maintenance free, to a large degree and as has been stated before, ability to deep cycle the AGM.

LED's are low cost and Quick to put in and cut demand on the system.
Before AMG install a 4 stage charge controler is a must if the AMG's are to last.
Best is a Pure sine wave Inverter charger that output's 120 Volts AC.
then add 200-400 Wats of Solar to finish system mine has run 4+ years.
The best webb sight is A&M solar, read all of it before you start.

I opted to do ALL OF IT at one time with my new Classic. All of the OE lighting is LED (except for the Baraldi range hood -- for which I have already replaced the halogen bulbs). I added the Magnum MSH inverter...which has a highly sophisticated inverter/charger set-up, as well as a 600W AM Solar package. 4 Lifeline 6V AGM batteries which are INSIDE the trailer. Granted, a fair expense, but no trade-offs for off the grid trailering. Also, no worries about battery overcharging with a high-quality system. For dire straits or A/C, I have a Honda EU3000i Handi.

I thought AGM's typically had less amp hours for the same size as their wet cell counter parts. This has been my experience.

Also, LED's first.
