I've had my 19SBR for about 2 weeks now. I haven't been able to take it out yet. But I should have a shake down in the next week or 2. I've also never owned a travel trailer before.
I love my 16BH and hope you enjoy your 19SRB as well. I've only gotten out twice with mine and am still learning about it and how we are going to use it.
I had knee surgery this week and hope to get back to camping soon – as soon as I'm able to climb up in it. I can let Mark do the set-up for a couple of times
Here's a link to a thread which is about the items needed for basic trailer operations. Like yourself I'm pretty new to the world of TT's and wasn't sure about everything. The advice I got is invaluable!
