If they're not used to being in the MH when you're not there, I'd strongly recommend some practice runs before you get to FW so you can figure out the best setup. You can even do this at home in the yard.
We crate our dogs in the TT, but they're very happy and comfortable in their crates and often hang out in them with the door open at home. If your dogs are happy in their crates, I'd recommend bringing them. If they're not, you might want to work on crate training before your trip.
Big reason we crate our dogs is because if we didn't, they'd be in the windows all the time barking at everything that goes by. Instead they hang in their crates with the TV on, fan or A/C for white noise, shades down and a nice stuffed Kong to keep them occupied while we're out. For our dogs, if they can't see/hear anything outside, they aren't going to bark.
The kongs keep them occupied while we slip out the door, so they don't even notice we're gone. I will either stuff them with yogurt/kibble and freeze the night before, so they essentially get their meals that way (keeps them busy for a while) or just put a smear of peanut butter and a cookie inside. Almost every time we come back to the TT they are sound asleep and the kongs are licked clean.
Works like a charm and we've never had an issue or complaint.
We have very active dogs, so we also make sure to get them out in the a.m. before we leave for the parks so they can run and get good and tired. Dog park works great for that (IF your dogs are very social and have good experiences with dog parks). They get play time later in the day/evening too. Both ensure they don't mind chilling in the TT in between.
When we're hanging out
with them at the site, we bring tie outs and their x-pens. Remember they have to be leashed at ALL times except at the dog park, and you cannot leave them outside the MH unattended at any time.
Our dogs thrive on routine. We establish a routine at FW and within a couple of days they've got it and it's like they've lived there forever. This year will be our 3rd 3-week trip to FW with the mutts, and they really seem to enjoy it. In fact our older dog - whose been to FW the most (4 times through this past year) seems to "remember" the routine about halfway through the first day! We usually do a few practice runs before we actually leave for the parks - take a quick loop out and about, sneak back and make sure they're quiet. We leave them for about 5-6 hours and then come back for potty breaks/meals/play time, then go back out for a few more hours.
Biggest thing is to know your dogs well and don't throw anything too new at them or suddenly expect things from them that you wouldn't normally at home. Keep it easy for them, even if it means a little extra work for you. Trust me, in the end you'll be glad you did and
ALL will have a terrific time.
