2007 Wildcat TT25w/slide

[tusonbird]

I'm thinking of buying a used travel trailer. I have traveled in a motorhome, fifth wheel and trailer but now down-sizing and would like to stay under 29 ft. I will probably buy a used rig as I'm almost 80 and travel alone (meet-ups with friends here and there) so may not have enough years left to justify a new purchase
I have a GMC Sierra 2500HD 4WD with the heavy duty tow package so I know I can pull a small trailer without any problem.
I'm going to look at a 2007 25' Forest River Wildcat T25 w/ slide this coming week and wonder - - if its in good shape is it a reliable rig. I've heard good things about Forrest River products.
What should I check for in particular besides any obvious (or closeted or inside cabinet) signs of leaks? Do I need to bring someone who can check suspension and other stuff under carriage & also rooftop?
Any help, advice or tips would be appreciated.
