There shouldn't be any supply disruption due to the Russian oil import ban. Last year the US only got about 3% of its imported oil from Russia. About 61% of the imports came from Canada. The Russia ban won't even cause a ripple in the fuel supply. The US is still oil export positive. Pricing on the other hand, is anyone's guess. My attitude is "Pay is pay it or park it." A $1/gallon fuel price increase adds $120/1000 miles, and I can handle that. Not happily of course, but we'll keep right on living and moving in our motorhome even if it means cutting the budget in other areas.
