Refliectix: a Must Have!
Took my 228 on a maiden voyage 2 weeks ago. Felt drafty in the bunkend (way more than in a tent with a fly on top) even though it wasn't terribly cold outside. Read about reflectix, put them in before last weekend's trip and wow - what a difference!
I'd estimate that the pup stayed at least 10 degrees warmer than without, and no draft - even though a considerable wind storm popped up just after midnight. I'm sure there was wind coming through and heat leaking out other areas, but the fact is reflectix covered 75% of my bunkend surface area and I'm sure the popup gizmos on top would make it even better.
I've read many threads where people say that reflectix might help, but I'm here to say it will be the best $50 investment you can make. And they really don't take that long to slide in. I just told my guests to look under the bed when they were ready to turn in and slide them in, and I did the same when I went to sleep. Quick, simple and effective!
