We weighed our Rockwood 2604 last March for our FL trip, loaded as heavy as it would ever be since DS#1, his wheelchair, extra food and who knows what else was in it. Don't remember the numbers, but we were close to max that trip. Normally it's just DH and myself + 1 medium size pooch. After realizing how close we were, I took a long, hard look at where Rocky could lose some weight. Our dishes, glasses and cookware are pretty minimal, bedding and linens are ok although we have a few extra bath towels that stay onboard. Where I found the biggest weight gain is in the pantry items that stay in the trailer for "those times". I hadn't considered canned vs boxed items. When we got home I swapped out a LOT of things that could be replaced with a similar but lighter item. Weekend trips are not a problem with frig loading, but on an earlier long trip I tried to shop for too many days and the frig was FULL. Lesson learned is that the frig and freezer don't work as effectively when packed to the gills....just plan to resupply more often. For 2 of us on a longer trip, I only buy for 4 or 5 days max and you know there is a Walmart just a few miles down the road anyway. We hauled around a Dutch Oven for 6 years in our HTT when we only use it once or twice a year, so that now lives in the garage with the other camping misc until we need it. We pack clothes for about the same # of days as for food. That's why campgrounds have laundry facilities....besides, you meet some great folks and chat while the laundry is doing its thing. It adds up really quickly. I've often thought I should bring the bathroom scale out and when the grocery bags go into Rocky I should weigh them to see what it really is.
DH had a cabinet in our ROO designated for tools and misc for whatever. When we moved things into Rocky, he found stuff he'd been looking for forever....he lightened up considerably.
We pull out of the driveway with maybe 5 gallons of water in the black tank and close to nothing in the FW, with the grey empty. We always camp with hookups, so why haul around 300# or so for nothing? And, contrary to many, we dump after every trip even if it's just a weekend. Longer trips, we dump every 3 - 4 days.
I have to admit that I have a small handful of "stuff" that I could take out, but it all doesn't even weigh 10#....seriously. A couple of plastic trays, a wine decanter that was a gift (also plastic), some very cool seasonal napkins. But Rocky is on a long term Weight Watchers because it does sneak up on you.
