Spring, Tx to Rawlins, WY

Hi everyone, new guy on the forum here. I was in the need of some advice. I will be driving to Rawlins,WY from Spring, TX, I will going up I-35 to El Dorado, KS to pick up my travel trailer since i left it there (from my last job assignment). My dilema is i was intrested in taking the hwy 130 route in Laramie to Saratoga, that's where I plan on staying 'cause the campgrounds are all booked up in Rawlins (I will be working at the Sinclair Refinery in Sinclair). How bad or good is this road? Are the climbs very steep? I have driven to Cheyenne before but that has been the longest trip yet and it was all interstate driving. I will be towing my 32 ft. Catalina BHDS with my 2010 Dodge Ram Laramie 3500 DRW. :@
