hi, we have camped for years and years with many different units over the years. I have owned two Citations (5th wheels)both with slideouts and never ever have I had a mouse in any unit that we have owned. They were all sealed off nicely at the factory. We have now purchased a heartland big country 3450ts and after having had it only a week found mice in it. Hubby found a mice nest in the front where the batteries are. So now we are fighting to seal it up and all the other places they are getting in. I have been told that they dont seal it in the front because if you use a generator in there it needs to be vented. They sure could have done that differently and sealed at least some of that up but they didnt. I feel that there is no quality control with these units as there are so many things that have to be fixed in them. I saw ours at a show and fell in love with it. Of course all the lights were on there and now I know why. Its so dark in there that you need the lights on to see anything, due to the fact that there is only one small window by the stove. I miss my skylights that I have had in previous units. The tv has been mounted as far to the left as they could mount it and none of the controls are accesible. There are so many things that need to be corrected they are too numerous to mention. Im not sure that I would consider buying from heartland again. It all looks good till you get up front and personal. Sorry I dont mean to be negative but all these things add up to not being a happy camper and heartland should know by now that the best advertisement in the world is word of mouth.......
Prior to our Landmark we had the trailers you mentioned, with the skylights, we loved it. we had the 26 ft 5er and the 32 TKS We loved that too. Prior to buying I spent many months on this site. The selling feature is the customer service, something I did not get at general coach ( out of Oliver BC).
We had the same kind of problems mice etc, we blew up tires like they were going out of style on both trailers. The GC trailers came with under rated axels etc and no CS.
what I am getting at is I had citation but made an informed move to heatland due to CS and product. I can send you the pictures I took of the Citation and the mouse entry points I sent to General coach to no avail.
when I get a trailer I do my own prevent procedures and leave a little something for the critters.
Don't be too hasty to condemn, I live in Saskatchewan, mouse infested.
Enjoy your trailer, open the blinds see the thread from when I was asking about sky lights, this was before we purchased, we love light but still purchased.
