Small cars and back seats a a definite no no for me..

I found my seabands on Amazon for around 6.00 but I bet the drug store or Wallyworld carries them….they really do work… We did a Blueridge parkway trip in a Camry… and I didn’t mark a single spot… only had to gulp out the window like a dog once….

I don’t think its right to let him live in his car

If he needs help, you should offer him a bed and some hot meals – Remember, no matter what, losing a job can be traumatic, so he will need your support. That does not mean “tough love” is not called for. **Just don’t give him any money**.
He may continue to spend what little he has on MLM products – its ok – It will eventually dry up and he will accelerate his path of discovering the truth for himself. The rest of it has already been covered ….

Good luck!
