vinyl wood planks or engineered hardwood

I am kind of amazed at home many different products and opinions are out there. I wish there was just one manufacturer that said "this works great in RVs" but wishful thinking, I guess! I was ready to go with Allure until Ernie Ekberg in Texas, a known flooring installer, said he's heard too many bad things about it... he recommends Mannington's Adura luxury vinyl, and never floats, always glues. Brannon Hutcheson with Tiffin and owner of Custom RV Inc in Alabama says he has installed 10+ RVs with Allure and has had no problems at all. He also likes Nafco's luxury vinyl tiles, which are stick down and "groutless". So I called our local (Memphis) flooring supplier to ask about Nafco in stock and he said, "never use anywhere but in a regulated environment, between 55-85 degrees". My head is spinning because we do NOT want to have to re-do the whole floor a few years down the road, and there are so many conflicting opinions/experiences out there. I will be sure to let you all know what we go with, and after the installation is done in late August I will post pictures and hopefully remember to give periodic updates to how the floor is holding up.
