Are thinking new or used? For new, some have very long wait times. Used might be worth considering if you have chemical sensitivities. Pretty much any molded fiberglass trailer is going to experience some initial off-gassing.
Gordon's suggestion of a rally
is a great way to see lots of different makes and models in person and chat with owners. Some have scheduled "open house" times, and even if not, most owners are happy to show off their units. Contact rally
organizers for advice about scheduling a visit.
Happy "egg hunting"!
