We have had our 291 Tg for two months now and still have the problem with the outside kitchen door.
The supports on our 2011 were too heavy and popped right off the foamcore door the first time we used the trailer. We have been told by our dealer that keystone is well aware of the problem and will send us a new door and supports to fix it. (still waiting) We have encountered several other owners with the same problem as ours. Either the supports are too light on the 2010 or too heavy on the 2011. Either way, be very cautious, it will come lose and pop off.
Before purchasing this our second keystone, we did look at the rockwood 8317SS, but finally decided on the layout of the kids room in the keystone to be slightly more to our liking because we can fit a 19" flat panel tv for our kids above the wardrobe, which is not possible in the rockwood. Not to mention that neither trailer were easy to find
We pull with a 2010 ram 1500 with a Hemi, and I would not really want to try to pull the overall length and weight of the 303TG with a 1/2 ton. Another reason we went with the 291. Just dont feel comfortable taking our towing capacity to its highest level of 10,000.
Hope some of this helped
