I tend to pack the small tent that allows me to be bit more flexible with the other items I wish to take. - I'm only planning the sleep in it and if you need living space if the weather is crap... why did you go there on a bike if the weather was that bad? I just take a trap to put up if it chucks it down.
I also like to plan my meals as I suffer with IBS, so hoping the local shop has something that won't make me spend most of the trip looking for the closest bog is a bit risky.
And then I tend to carry the beer with me - that way I can crack open a can even before setting up camp as I don't need to go anywhere... not every site has such a nice owner who offers free rides to the pub/shop in his taxi.
I'm no lightweight, the mrs is no rake, and we loaded the Wee and toured Scotland a few years back... blimey that was 9 years ago!
I think I worked out there was something like 60kg of gear.
Took a few miles to get used to the weight, but after say 50 miles I didn't notice too much.
By the time we were on our way back though mid Wales I was easily over-taking, even leap frogging a group of Germans on GS's. The ride leader held out a while until his group has fallen well back and he pulled over to wait for them. None of them were 2up or as heavily loaded.
Everyone looks at the 650cc bikes, as if they are the baby bikes and couldn't possibly do what the 1000cc does... any they'd be wrong. The 650 is such a good balanced package it does everything nicely.
I never felt I was wanting for anymore power. I've had a 1000cc bike for a few years now, but the Wee's and Glee's I've ridden in the last few years still make me grin and I'd happily have another one.
I've scratched the 1000cc itch and the novelty wears off after a while, plus the mrs out played me in bike trumps when she bought a GSX1400.
