Patodonn.... I've made the trip from Sacramento to K. Falls so much, my car can do it on autopilot.
I have sent email to the "K.Falls" sister asking about any decent RV parks in the area. She & her husband attended the Lake Siskiyou rally last month as our guests. She will hopefully respond tomorrow or I will call her. (She'd kill me if I called her right now at 10:30pm).
Nothing to fear from 97 to K.Falls other than cop cars, and be sure to go slow thru the town of Dorris. It's the last town before the CA/OR border and has some tight curves.
The "Dunsmuir Pass" on I-5 before you get to Weed is a bit of an upwards haul but you should do fine.
Here's some I-5 highway "cams" of the area...:

Three good stops for gas/diesel/food etc:
1. Rolling Hills Casino at Corning, CA. Liberal Road exit, go over the overpass and turn left on Barham Avenue immediately after the freeway overpass. Enter the driveway past the casino just before the gas station. Park in front to the right or go back and to the left and park with the semi-trucks. There is construction going on behind the casino where RV parking used to be. A good place to stop for their buffet. Ages 50 & over get the senior discount! They also have a gas station there but we've never used it. Don't bother throwing your money away in their slots.... they are tighter than a tick and don't pay off.
2. Flying J at Corning, CA, "South Avenue" exit, (exit 630), nice and clean. Also has a restaurant in it.
There's a "Petrol" across the street but don't waste your time there.
3. "South Weed" exit. At the stop sign go right and you'll see the gas stations & food joints. Semi-trucks stop here also. Easy return to I-5 so you can go a bit further to take the "97/Klamath Falls" exit. Last good place to get gas/diesel before hitting K.Falls.
"K. Falls sister" only recommends these to stay at:
She says all the RV parks in K.Falls city are mostly "12 months a year extreme low-income living" and your Montana wouldn't be too safe left alone. Better to go to campgrounds outside of K. Falls city limit.
