I have the leisure-lite.
We love it. Believe me when I say, we don't know we are towing it. With saying that you must remember as it is wider then your bike and you can hit things with it.
Some other things for you to consider other then weight.
What size of bed do you sleep in at home?
The leisure-lite is only a double. We sleep in a double at home so we love it.
Is speed of set up important to you?
If you can get to a RV show, they should have them there and you can compare in person. That is what I did. I asked them to take them down and put them back up to see what I would have to do. We laid on the beds also and stood up inside to see what the space was like to change and put things.
Ultimately, no matter what you buy, if you use it, you will love it.
Happy searching.
