Hi Ken & Barb!
When we started looking for a lightweight trailer, I started by researching 'pop-ups'. Be really careful - they are frequently much heavier than FG. This was a surprise, but now we're glad we don't have to worry about setup and/or wet canvas as we travel. The T@B retro-teardrop had just come out at that time, but was (and is) way over our budget ... which led us to this WONDERFUL website and the acquisition of a gently used
Scamp 13.
We tow with a 6 cyl Mazda MPV and have had no complaints BUT we also have NO illusions about how much we can carry total in both vehicles. When something new comes in, something old goes OUT! We don't have trailer brakes (yet- perhaps when we have to replace the axle) and seldom run over 55 mph. As we say, YMMV ...
According to the Kelly Blue Book website, the 4 cyl 2.5 litre is rated to tow 2000 lbs. - guess that would work if the trailer you find has brakes.
Happy hunting! Whichever you choose, we wish you safe journeys and many happy memories! Regards, L 'n D
