TKConn... unfortunately going with an HTT will not solve the problem you encountered with the rain. As a matter of fact, on our last trip, the winds were really bad while camping by the beach and my wife got no sleep because of the tent ends inflating and deflating with the wind and making all kinds of noises with the shepherd's poles. I want to say the one shepherd's pole came undone twice because the C clip on the end is partially broken.
We upgraded from a PUP and even though we didn't get rid of the hassle of dealing with wet tent ends (on some camping trips), it was still a great upgrade! Good luck!
Not sure what time of the year you are coming, but if you like the beach, I would recommend Gamble Rogers Memoria State Park. There are only 30 sites and they book quick, but you are basically on the water with red sand! Do try Ft Clinch.
I have been towing our 19' HTT (2,700 lbs dry weight "whatever that means") for 2 years now with a 2005 Odyssey EX-L.
Yup, I installed the hitch, 7 pin wiring harness, transmission cooler, steering cooler, weight distribution hitch, fresh transmission fluid every year and the van has been doing great!
We do live in Florida which is mostly flat lands and we never drive to campgrounds that are more than 3 hours away.
Yes, you will feel the wind resistance with the frontal area of the HTT and that's why we drive at no more than 55mph.
Our setup is totally maxed out with 3 bikes on top of the van and 5 children under 8.
I don't know if you were asking about the max tongue weight, but I believe it is 350lbs.
Not sure if you are referring to an "extendable" as one of those TTs that have the rear bed that slides out in a hard shell, but if you are, I can tell you that there is a family that camps with us and they have one of those with bunk beds on the front of the trailer (4 beds) and a slide out bed in the back and their A/C has no problem keeping up with the Central Florida heat. I hope this helps. Oh, and their A/C is ducted (sp?) so it comes out of different places in the camper; where as our HTT only has that central A/C that only blows out from the middle.
We mostly cook outside. That poor stove that attaches to the outside of the camper gets used on every trip. I do make coffee inside in the morning, though and sometimes have to use both outside and inside to get breakfast ready.
I don't know if I missed this, but what state are you in? I paid $5k for a 2001 2 years ago here in Florida because there was nothing in my area for less than that at the time. Yes, if I had waited more months, I could have probably ended up with a different price, but that's what there was at that time.
Some great points here... I like what wmoses said about getting the humidity level down. That's probably the biggest thing in comfort in any environment. To the OP, are you talking about keeping the HTT cool during the day or at night? Here in Florida we don't have the heat you do in TX, but it has gotten up to 100% humidity and 98 or so in Central Florida. Our HTT has had no problem keeping it cool inside, but only with the help of reflectix (can't say anything about PUGs 'cause I've never used them).
We put window inserts made out of reflectix and that made a huge difference for keeping the cooler air inside. At night it has never been a problem even if the temperatures don't drop below 80 (in July).
We have had our twins sleep in the bunks during the hot days and it was very comfortable (not super cold, but cold enough that we had to lower the fan from high to low).
BTW, we don't have a ducted A/C and our HTT is a 19 footer.
Hope this helps in some way.
I don't know if it is the wind or expanding/collapsing of the awning, but it seems that the place where the awning attaches to the HTT has experienced a slide of the awning canvas. So, when I retract the awning, I have a hard time pushing the 2 arms to lock into position against the camper. So, I've had to have someone help me push the arms towards the front of the camper so that they align, but you can see that the rolled up awning doesn't roll perfectly. How can I slide the awning forward so that it rolls perfectly again? I wish I had a picture to show what I'm talking about.
