Easy way to determine how much Travel Trailer I can buy?

Sorry to offend Walaby. Yes, I have been a member since 2005 but I don't buy a new travel trailer often. I have not been actively keeping up with the forum over the last few years but have always gotten great advice and feedback from others on this forum in the past. We need to stay around 6000 lbs. Just needed a little refresher on the subject as I work to set realistic expectations for myself.
Thanks to everyone for the feedback. We can close this topic now.
