NH Teardrop (What's your name BTW?)
There are other gatherings scheduled around the northeast that you can check out as well. If you haven't done so yet, you should head over to the TearJerkers site (link is above in the menu) and register there. Once you're on that site you can check out dates for other gatherings around New England, New York, PA, New Jersey etc. Just click on the area chapter that you're interested in. Anyone is welcome to go to any gathering. You don't have to be a member of a specific chapter. I know that the New England chapter has a few members in N.H. but I'm not sure how close they would be to where you are.
If you really want to see alot of trailers at one gathering, see if you can get some time and come up to the Adirondaks the weekend of June 9-12 (or at least part of that weekend). There will be alot of teardrops at this gathering. Again, you don't need to have a trailer. I camped in a tent the first year I was at this gathering. This is not a TearJerker's gathering but there will be alot of members there. Here's a link to the thread on this forum for this gathering.

Seeing these things up close really makes a big difference in your perception of the space inside. If you get to a gathering go right up and ask some of the tear owners for a tour. Alot of folks will let you climb in to get an idea of what it feels like inside also. Seeing a few in person will probably help your wife get a better feel for the space.
