solar yes!
we started out with eagle shell to keep it simple,solar keeps it simple,we use a 2ftx4ft glass 75 watt panel mounted on roof,keeps it out of sight (it is 2007 and things do disapear from camp sites!)also have seen panels broken when free standing and the wind comes up,as we tend to stay in spots for longer periods,well at lest 1 night or more!it serve us great.with 1extra battery,it lets use use inverter to charge cell phone,gps,2-way radio's,reg radio,air compressor (to air up dual-sport after trail riding),sat.tv receiver, tv,fan's (it gets hot here in the desert)and best of all engle 45 12v frig/frez, i don't worry about parking in sun,if shady ok still charges 2+amps (desert shade is thiner than mtn. shade!) in full sun 5amps laying flat,if tilted (which i used to do until i found it was charging fine flat)7amps,have used this panel and controller for over 10 years with o problems.your usage may vary!,just my 2 cents worth. drive slow and enjoy "its the journey"
