Greg -- I will add a slightly different perspective. I
sold my
Scamp 13 DLX to purchase a teardrop. For my needs, I went with a LittleGuy 4-wide Retro. My wife and I have used it several times since we purchased it in September, and are loving it. I can tow it with my Saturn SW2 wagon, and get roughly 30mpg. It is 4-feet wide, which gives as much bed space as a typical fiberglass camper, but the advantage is that the walls are on both sides, and straight. So, one person doesn't lose space to curvature while the other feels like they are falling off the edge. So, from experience, I would argue that teardrops sleep better than most larger fiberglass campers. If sleep is your primary use of a camper, I think the teardrop wins, hands down.
However, as has been pointed out, teardrops typically are pretty limited on space for much beyond sleeping. That is a significant difference with the
EggCamper teardrop. Looking at the pictures, it isn't a typical teardrop. First of all, based on the measurements, it appears that the shell is 10' or 10.5' long - as long or longer than a
Scamp 13. It appears that it has a seating bench in the front, a small floorspace for legs while seated, and then a sizable bed of at least 60" wide (how does
that sound to most folks reading this?!) The height isn't stand-up-and-stretch tall, but it certainly is get-dressed-fairly-easily tall. It even appears to have plenty of room for a porta-potty. As far as cooking out in the rain, well ..., there are compromises with any choice. With our LittleGuy, we have a 9x12 dining canopy, and just park the teardrop under the canopy, so we can cook in the dry.
Since you are coming from the teardrop world, and no doubt have great associations with your experiences over the years, I think the EggCamper teardrop is a very viable option for you, assuming your wife comes to think along the same lines. If she doesn't, I think I'd recommend going with her choice.
By the way, the Eggcamper teardrop is a fully-qualified Lightweight Fiberglass RV, and this forum had better get used to the idea, because with gas prices what they are, we are going to see more and more campers such as the Eggcamper teardrop. My two cents.
Best wishes on your quest, Greg. Just make sure that your wife is happy with the choice.
