I had an Escape 17B for 6 years, towed it almost 100,000 miles around the US & Canada. 3100 pounds loaded, towed with a RAV4 & a Tacoma. While I loved the trailer, I wanted an oven, full time bed & 4 person dinette & a built in microwave. Sold the 17B (in one day) and moved to an Escape 21. I've been in it for a little over a year, dry camped for 3 months at Quartzsite (without a generator) and am currently on day 78 of another 7-8 month trip.
Fore me, the advantages of fiberglass "eggs" over stick built trailers are lightweight for the size, minimal need for maintenance, and a wonderful group of owners that love rallies!
