Upgrade?

[captmath]

We were on the OBX last weekend and my DW was surfing the ETI website. She started looking over the specs for the 5.0 TA. We had talked about it before and she really likes the tandem axle. But I don't want a bigger truck. She was looking over the options and locked onto the screen room. "This one is a lot bigger than ours!" Me: "But I don't want a bigger truck.''
That stopped the discussion for a while until she found a picture of another Frontier pulling a TA. More discussion. Much more.
We were headed home the next day. When I stopped in Hampton for gas, a young man followed us into the station and asked to look inside. He seemed very interested and gave me his contact info "just in case". (I gave him an ETI card.). DW takes that as a sign that we should really consider the change.
So--would I need a bigger truck? I am very pleased with the performance I am getting with the Frontier + 5.0 combination, and I read somewhere that ETI was designing the TA to be pulled by a larger vehicle.

Any advice?
