Gx85 for Travel?

Hard to comment would GX8, or GX85 be better to travel since it would be highly dependent on your own condition and style of travelling. A few posts in another forum said carrying few Kgs of gears are pieces of cake to them, or if one traveling by self driving and visiting places just be a few steps from the parking car, what to carry is not a consideration at all.

Speaking on my own experience (join a tour group, walk for hours a day touring around old town, ruins, museum, palaces etc) I must carry light, and have lenses covering the widest focal length with me all the time. I used G1, later GX1, then GX7 and now GX85 (but would fall back to GX7 as my wife like GX85). The size and weight of GX8 is definitely not my cup of tea. In fact, except for the weather sealing, GX8 doesn't likely give me more than GX85 for my travelling need. However, all of my previous Pany cameras were well proven under various adverse weather condition from heavy rain, snow storm, -25°C cold, dry desert etc and none of them failed me before I upgrade. Basically weatherseal means nothing special to me. YMMV.

As I must carry all of my lens with me for the few hours walking every day of my trip, I always have 12-35 f/2.8 on my camera, 7-14 f/4 and 45-150 in my bag. A total weight of 700g hanging on my neck and around 600g in my bag on my shoulder only.

Joining a tour = quick action. I don't have the luxury to walk around for human zoom (very often impossible) and change lenses dozen times for a single target. Zoom is my best friend.

Fast speed is also not a must as I rarely shoot fast moving object indoor/at the night. In dim lighting indoor like cathedrals etc there are always a lot of support I could making use of (e.g. wall, pillar, bench, handrail etc). I could use G1 well in the old days (usable ISO of 200 only), upon the improved ISO of GX7 (ISO1600) or GX85 (ISO3200), also the excellent Dual IS of GX85, I am now never happier. Although a mini table top tripod might sometimes be in my bag (for the human image stabilization system as per lovely members' teaching), it was rarely needed.

ADD: If GX85 be your choice, I strongly suggest you to buy an USB charger instead of using the in-camera USB charge because upon charging, the camera must be switched off. I used something like this:
