I have two smaller renogy 100 watt panels on the roof of my 1983 Grandby.
I have room to fit one more 100 watt panel (while still leaving the other half of the roof open for surfboards), and I may do this in the near future.
Make sure you have gas shocks to help raise the roof as it will get pretty hard with 200+ watts on the roof.

2 160w panels. I don’t see the weight being an issue. It’s roughly 50 lbs spread out over 2/3 of the roof.
If I had one over the cab area it might be different because of leverage lifting the front.

i had 600ish watts on an older hawk - doesnt leave room for anything else but fits just fine
lifting = not bad

I am in the process of replacing two 100 W panels on my FWC Keystone with a single 370 W residential size panel. Total weight is about the same, maybe even a couple pounds less.
I recently posted some dimensional and weight information for a representative list of larger wattage (<200 W) solar panels along with some FWC camper roof dimension info at the Wander the West forum at the following link (skip down to post #9 for the embedded spreadsheet):

What are the Measurements of the Roof Vent Locations on Your Camper?
Recently I created a speadsheet comparing the sizes of various Renogy rigid solar panels and the power and weight of single panels vs multiple panels. The results clearly show that using the largest single panel that will fit is seriously worth considering in order to minimize weight, and cost...

i may have some pics (search my post history)
i had 300ah of lifepo4 running off a 40amp mppt controller (the panels were run in series) - i would typically hover around 20-24amps at peak
i will note: rarely parked in full sun, and mostly ran the that setup in fall/winter

There is a lot of variation in the construction of these roofs over the years. MachineBuilder's pic, above, is of a newer camper. The older roofs sometimes sag in the middle (fore/aft) a bit with any type of load.
There's plenty of space on a Grandby roof. It just depends on what, if any, space you want to leave free for other items.
