I find the doors stick when the trailer is in the sun and the decal on front door melted to the door grab handle when it was folded closed. I contacted Grand Design and after sending photos and several e-mails I was told they did not have a fix for the problem. I read on a forum where numerous people are having same problems. I mentioned this to the Grand Design service rep and was told I would not have this issue in the winter as it was not hot outside. I also asked about a heat retardent and was told there was not one. I asked if the problem had been presented to the design team and was asked was I saying this was a Grand Design problem or Lippert Components as they manufactured the door. I sent a reply back asking about the air gap at bottom of door and the melted decal on bedroom door to see if they were going to do anything about this. Waiting for a reply. I purchased the Transcend after much research having owned other brands of travel trailers in the past. Ratings were very good on the Grand Design so I purchased that brand. Rating showed good quality and great customer service. Now I question my decision. Another issue the light over bed went out after a couple months (had trailer less than 6 months) took in to the dealer for repair and some other warranty adjustments, took over a month to get the light fixture. With all the individuals having the door expansion issue and not cooing the Travel Trailer, has anyone found a solution? I feel Grand Design should fix the issues with doors and cooling as they say they will resolve problems. To be told I will not have this problem in the winter makes me really question what kind of customer service Grand Design has. I would have some serious issues recommend this company for service and warranty. The layout for the Transcend is great just not sure how it will hold up. Show less
