We didn't order a Winnebago but when we did order our motorhome it took around 9 weeks. Let me tell you those will be the longest weeks of your life. LOL :D We ordered in Dec. and it was at the dealer towards the end of Feb. Yeah I think this time of year when they are gearing up for summer that mid March is wishful thinking...
Be sure when you order that you go over the options several times and give yourself some time to think about it. There are still options that I wished we had got and some I wished we wouldn't have wasted our money on. Our biggest mistake was getting the queen bed instead of the king bed that was just dumb on my part. Why we paid the extra money for the outside TV I will never know, we never use it... So be sure you go over the options carefully and take time to think about them..
