We order our 2306 with them. Have not camped with the TT due to obvious seasonal reasons. This year we are going to see how well do in the summer and perhaps in the winter.
I was working on the TT one time and the temp outside was around the low 40s. Inside the TT was bearable; a good sweater can get you by without the heater on.
I say get them if you want to pay the extra, every gain of R Value adds up.
