This routing avoids most of the SUA airpace (sans Shoshone and Panamint) but the Death Valley fly over is well worth it. Altitude requirements are very reasonable for your A/C type. I often fly straight up DV at a reasonably low level (for the National Park) and if the winds aloft are not screaming you should have a very good ride this time of year. Joshua has good radar and VHF coverage in this area for flight following if you wish. R-2502 is almost always hot so don't expect that shortcut but it never hurts to ask. R-48xx is pretty much the same. I am a avid desert flyer and seeing the basin and range in DV and in the heart of Nevada from the Mooney is one of my favorite things in GA. If the weather is good the flight will not disappoint. (btw, We fly a C as well). You may as well take advantage of this opportunity to see this awesome desert. KTPH and KEKO are good relief and fuel stops along the way. O5U is a little more pricey for fuel but still acceptable. If you need an earlier stop L06 or KBTY would work as well (but no gas). You can easily vary this routing for terrain and in would be a good idea to stay on the upwind side of the valleys. Fallon, Owyhee and Jarbidge MOA's are worth avoiding but ZSC or ZOA can give you updates on activity along the way for a more direct routing to your destination if cold....You can save a few miles transitioning though the MOA's after BOU if able....I would definitely recommend ATC flight following in this area and get a clearance for a Boise Class C transition if you haven't got a shortcut trough the MOA..
Sounds like a great flight and much fun.......
