Stockton to Bakersfield(Arvin) 99 or I5

I took I-5, seems was a little better than last time, cept Sac>Stockton....sections south of Santa Nella to Bakerfield are terrible in right lane. May try 99 next year if I have to be in CA.
thanks for all the suggestions.

I always pickup 99 in Stockton on my way to Bakersfield.

Pulling 6200# with Ford Expedition through Jellico Pass in TN. Any Comments?

1 5 for sure !! But beware drivers passing you going 80 90 mph

99 has had a lot of work done and is fine.

neither 99 or I5 are good drives or good roadways. if just getting from point A to B is the goal, I would use the 5. Driving a big RV in the right lanes of 99 is very frustrating with all the frequent on/off exit/entrance traffic constantly cutting you off.

Recommend 5, traffic will be lighter for me on 99!:B

Roll the dice on this one

I5 is quicker a lot of in and out traffic on 99. I5 is boring! Both are bad roads, so take a pick.

I would take I-5. Less traffic on an off all the time.
