Will a Select Suite 36TK3 give me quiet retreat from noise?

Will a Select Suite 36TK3 give me as much quiet at night as a Mobile Suites or Elite?

I ask because I am very pleased with a 2007 36TK3 Select Suite 36' model I found but several experienced RVers have told me, "That's the bottom of the line. Wait for a deal on a Mobile or Elite if you want solid construction and quiet."

This RV is for long-term, year-round living on a single site. I heard that the Select Suites used double I-beam instead of box-beam----but will that truly impact my quiet (and my sense of being inside a more "house-like" structure in terms of sound transmission?)

I am a little concern that the 14,640 weight of the unit might represent less wall/roof/floor and insulation thickness???

And that reminds me, is the insulation difference or quality in Select Suites less than those of Mobile and Elite? Is the Select more likely to have wall-condensation issues in eastern Texas winters about 100 miles from Houston? Or are they all much the same for that use?

I have wondered why people dismiss Select Suites as "it was the bottom of the line" ---because I don't care about the luxury features.

Considering that I don't need highway durability and the 2007 Select Suite seems like it should suit me, is there any truth to their concerns at all? Are there any important downsides to the Select Suite? (And I can't put off a purchase and search forever in hopes the right Mobile Suite will come along----unless it truly is a much more "full-timer" unit.)

Any and all advice appreciated! Thanks.
