Fan99, let me deal with the issues separately.
The dry weight of the 29RLS is pegged at 7,632# and the GVWR is 10,400#. By the rule of thumb that I have always heard you need to have a vehicle tow capacity that is at least 120% of the GVWR of the trailer. That means you need a tow capacity of at least 12,480# for minimum safe towing of this trailer.
Another rule of thumb that you often hear is find the trailer that you want first, then find a tow vehicle to match it. I'll admit I didn't do it that way, but I did pin down the size of trailer that we wanted before I went out to find a tow vehicle. I bought a tow vehicle that had some additional towing capacity [2005 Chevy 2500 HD Duramax (13,600#)] just to on the safe side. Then, before we ordered the trailer, I took the tow vehicle to the RV dealer we had selected and asked him detailed questions about the match I was proposing. When he approved the match we ordered the trailer.
That being said, from the 2008 Trailer Life Towing Guide (
http://www.trailerlife.com/images/digitaleditions/pdfs/DigitalTLTowGuide0801.pdf), it appears that the tow capacity of your 2009 Suburban, if it as XL with the 6.0 V-8, is 8,000#. My opinion is that you have too much trailer for your tow vehicle. You should either look for a lighter trailer or look for another tow vehicle. Just my opinion, but keep asking around. Get lots of opinions.
As to the NC 29RLS, I am very happy with it, but I must add that due to an urgent family medical situation that arose just after we ordered the trailer we have not been out in it, although we have now had it since late July. Selecting your dealer is probably as important as selecting your trailer. I am very happy with my dealer (Olivers Campers in Norwich, NY). One of the things that they told me is that there is no such thing as the perfect trailer. They all have issues and part of owning a trailer is being ready, willing, and able to deal with issues as they arise. The Heartland North Country is not the perfect trailer. We have had some minor issues while it just sat here in our driveway that cause me to question both the quality of some Heartland design elements and the workmanship that went into building it. The great thing is that between my dealer and me we have been able to address all of those issues and I am happy with the results.
Given what I know right now, given the limitations expressed above, yes, I would but the NC 29RLS again.
Hope I have been helpful.
