I am considering the following models of the North Trail Travel Trailer. They are the NT 29RTLS,NT 30 RKDD and the NT 32 RTLS. Does anyone have any info on these models and are there any major problems with them? Is there any difference in having an island in the 32 RTLS instead of having everything in the kitchen? is there more storage space with an island. Also, where is a good place to check prices? Thanks.
