I am in the exact same position you are! I have been in aTC for the past 6 years with 3 kids and we have loved it but literally have outgrown it. We picked up a used 2012 Springdale 249BHSSR last week. My wife loves the space and we like the bunks.compared to what we are coming from it feels huge. But for a 5th wheel it is still small enough and low enough for us to get where we want to go.
The prior owner put a hitch on it and we will tow tandem (motorcycles or boat), which is common in Colorado. With that said, I do plan to have the frame reinforced around the hitch to distribute any additional stress load. I have read here that many manufacturers dont cover warranty issues with the frame if you mount a hitch, but I am out of warranty anyway.
Overall i like the Sringdale so far, but many may think it is on the small side for a fiver. Quality is typical and it does not have all the bells and whistles that many of thelarger ones do. Our first big trip is this week to the CA Redwoods.
I am mourning my TC for the "go anywhere" ability but i knew this day would eventually come.
