I can't answer your question but I wanted to welcome you to the forums while you wait for others to drop in. If you can see the 176T in person why not ask the sales person to close the expandable tent. Also don't be shy to ask for alone time in any unit you are seriously considering. I'm glad I did because I almost walked away from my unit. The time without the sales person gave me quiet time to think over my choice.
Great choice for "Living within my means" and camping for one...
