Smaller Trailer, with big features, ideass?

You can pull a Keystone Bullet Ultralight 30' with a 1/2 ton . They weigh under 6000 with tongue weight of 600. I have a 31' Bullet 285RLS and pull with an Expedition! Bullets are Ultralights but with deluxe amenities and are high quality! I have only seen positive reviews on this and other sites on that model! Ours is a 2014 and we have never had the slightest thing malfunction after 3 years of use! That is amazing ( and unusual for a TT). Forget the W/D combo though.. as others have said you will only find in 35' and longer TT's and FW's.. and not necessary . Most F/S campgrounds have W/D's on site and if Boondocking, the nearest town has a coin laundry if you are staying for an extended period and need to do laundry.
Check out Bullet TT's on line or at your local dealer. Find a 2017 leftover and you will save many thousands over a 2018!
