I'm very close to pulling the trigger on purchasing a radwagon 4 but wondering if and when we might be seeing a radwagon 5. I don't want to buy a 4 and then in 3 months from now see or hear about a 5 coming out which would both drastically reduce the price of a 4 and also provide and update bike

I was wondering if you NEED to use the caboose along with the child seat or if you could do without.

Also wondering about some versions and when to expect a RadWagon 5.
