RE: On the road but scope ??
The Monarchs have just as good glass/features as the VX IIIs and are a good bit cheaper. Youll be very happy with the Nikons. While your there, check out the Bushnell 4200s Id take those over either of the other 2 brands.
Bushnell's 4200 have the best guarentee/waranty going. They half lifetime replacement for anything plus if you dont like the scope and want to return it anytime within the 1st year of purchasing they will give you a fullrefund of purchase price no questions asked.So if you dont like it on your trip you can get your money back.
