Get the DR 650. All you need to do is change the oil every 5000 miles and clean the airfilter, cheaper too. Nothing against the KTMs (I had a 950 for years and have a 500 I ride weekly) but they are more expensive to maintain, that said, I love them but there's less to go wrong with a DR. Of course, if you want to have a bitch'n time, get the 690 and if something breaks, you can get any part you want within 2 days. I sold my 950 after I had to pick it up a few times in one day in a sand wash in the Black Dragon Canyon, part of the old TAT in Utah. Big heavy bike and my friends on 650s were getting double the gas milage, so I also had to carry 2 extra gallons of gas. Of course, I also had 100hp . We've since ridden our DR 650s (my wife has one too) from the east coast down to Panama and back, then this summer rode up to Alaska/down to Baja and back (I had to replace rear wheel bearings & fork seals on my bike & rear brake pads on hers, thats it in 15,xxx miles). You will find camping is much easier in the US than say EU, look on the map and anywhere its green is usually a State/National forest and you can always find some stealth camping, especially out west (much easier). We spent 2 months riding to Alaska this summer and didn't get a hotel till Baja. Decent food is to be found everywhere for making meals at camp. For cell service someone else will chime in, but I think you can get a month-by-month plan with data from T Mobile pretty cheap? And there seems to be WiFi everywhere. Use the tent space here on ADV (great for meeting people) or iOverlander App for camping/food/gas (free) and I would suggest the OSM+AND for offline maps, just download a few states at a time and you're good to go for directions.
