I stay off super slab as much as possible. Especially 2 up as she likes the frontage roads and US hwy system.
She is good til 340 miles or so.
I put on sundowner seats on all my bikes and airhawk II on all seats and pillion. I love the air hawks.
Also I cut, welded and machined different peg mounts for her to get her legs less folded up.
We do that often. Usually leave Saturday and come back on a Monday.
I don't do much on my older 70s style riding and camping anymore. Maybe once or twice a year. The rest of the time I am in hotels or motels. If we are on on long road trip were we would run out of clothing we either wash or on occasion when we are covering ground I UPS a package to one of my "known" stops (only have a known stop ever 4 days to keep me from straying totally off course) with a return label as well. News clothes in old clothes UPS to house for her skirt work duties on return!
Please don't tell her I typed that. It would not go well for me.
Managing 350 miles a day is a good day's riding. If you can average 50 mph that's seven hours in the saddle and with stops (I make a lot of stops) it's easily a 10-12 hour day of riding.
I have a Sundowner seat on my Sportster and really enjoy the comfort. The stock seat wasn't necessarily uncomfortable but, for my 50th Annivesary Sportster, the stock seat had special embrodery and I didn't want to wear out the seat that I would have done. I've been told having a gel-pack installed in the seat would make it even more comfortable for long rides but not being uncomfortable now has prevented me from spending the money for it.
Like you I use motels (and like to find one with a jacuzzi after a really long day). I've thought about camping along the way sometimes in recent years like I did in the past but.... decided against it. LOL If I could find a very light and compact sleeping bag I might consider it but even back-packing sleeping bags are way too bulky for my traveling tastes.
In the very small leather backpack I use for road trips I pack it with 3 pairs of socks and underwear that are old and disposable. When dirty I toss them in the trash. If I need more I buy a new 3-pack on my journey.
Sending clothes ahead makes some sense but about 3/4ths of the time I never make it to my "destination" so that's a problem for me. I manage to get lost along the way. LOL I am thinking of wearing more "disposable" clothes in the future and, if for example, my jeans get too dirty then just trash them and buy another new pair. It would eliminate doing laundry on the trip.
